The break up part 2 in Stories of my life... literally

I was truly baffled and hurt by the way he had been treating me and i realized how little I actually meant to him. I had started to move forward but I still had this urge to talk to him. A few days after the dunkin’ donuts incident he texted me a long text message apologizing and claiming that I was right, he should’ve had more respect for me, that he was sorry. I forgave him and he said “I’m sorry and I’m still not over you” and somehow knowing that he still loved me and wasn’t over me made me feel better and a bit powerful and it was exactly what I needed to hear in order to mive forward. At that moment that’s exactly what I decided, to start to moving on. Me and diane started hanging out more and going out more, and she took a video of me and put it on her snap chat story. This guy that went to my school Gabe sent Diane a message with the video of me and the heart eyes emoji. Diane got excited for me and told me that I should use him as my rebound from Josh. Gabe was known to be a flirt and not serious with girls which is why I decided to add him on snapchat. We began to speak and flirt and see each other in school where we kissed a few times. He was a grade above me so I didn’t see him much but before he left school he would meet me outside of my class and talk to me. As we texted I found out more about him such as the fact that he lived on my block. At this point of the story it’s mid March and I’m happy, smiling again, barely even thinking about Josh anymore and finally accepted the breakup. But bam he texted me with a simple “Hey” and all the feelings came rushing back. We started texting but just normal conversations and Diane was there to make sure I didn’t say anything stupid. I tried not to care because I was finally happy again and I didn’t wanna get my hopes up just to be disappointed by Josh again. So I kept the conversation short and tried not to respond as much. I had him in my health class and we would smile at each other but still I tried to ignore him. So this is where it gets a little crazy and the bitch Callie comes back to the story. I was in spanish class with my friend Gia and she had Callie on snap chat and she said “Are Josh and Callie friends?” and as soon as she said that my stomach dropped and I knew she was going to tell me something that I did not want to be hear. I said “i don’t think so they haven’t been friends since freshman year but what he’s doing anymore. Why what’s going on?” Gia said “Well I saw on her snap chat story that she was getting picked up at work and I think it was him who picked her up.” I was beyond angry and i told Gia that if she saw any more snaps of them to show me. I told Diane and she was shocked and angry (she was friends with Josh too). A few days later Gia sent me a video of Callie and Josh walking at night holding hands with a heart emoji. I was furious and I couldn’t believe my eyes. Me and Josh had been talking here and there and he was flirting so I decided to confront him about it.
Me: “So what’s going on with you and Callie”
Josh: “Nothing we started talking and became friends again after we broke up”
Me: “Oh and that’s it? Because I heard that you pick her up and that you guys are talking now.”
Him: “No nothing’s going on between us we’ve just hung out and flirted a little but that’s it.”
I decided to believe him but I kept on talking to Gabe because I wasn’t going to let myself be completely vulnerable to Josh anymore. I planned on leading him on but not let myself fall in love with him and make him know that in order to make him regret his decision. As we talked more and more I started to gain all my feelings back. Josh and I hung out and we kissed and I still spoke to Gabe but not much. The day after the kiss Josh texted me “I just thought you should know I ended things with Callie” I responded “I thought there was nothing to end in the first place” And he somehow brushed it away saying that he wasn’t going to talk to her anymore. After that me and Josh we were walking around in school together and making our friendship/almost relationship public again. And I found out about more things he did with Callie from other people soon after like that they would hangout, go on dates and to restaurants, he brought her to his house and they cuddled together and that he said he was going to eat her out. I was furious because of what he said and did with her, that he was treating her like an actual girlfriend and especially that he lied about it. I confronted him about it once again and he apologized and said he didn’t do anything sexual with her he only said he was going to because he was horny. I told him that if he did anything with her or anyone else to tell me once and for all. He admitted to nothing. So stupid me forgave him again but I kind of became uninterested and was talking to Gabe more. I knew I didn’t want to be in a relationship with Josh anymore but I was scared to break his heart. By the time my birthday came around in April, Josh had gotten me a pandora bracelet with 3 charms on it. One said love, happy birthday and a little diamond. He had never gotten me something so nice without me having to tell him to. I was surprised, shocked, happy and feeling guilty. I wanted to get away from him and I got a ride home from my friend from school (so was he) and when i was dropped off he stayed back with me (even though i didn’t want him to) i invited him to my house because i felt bad. He admitted that he was so happy to be in my life and that he loved me and wished nothing but happiness for me. I had to be honest and tell him that we should just stay friends and that I had moved on, like he told me to. He bawled his eyes out and I politely asked him to leave. Later I was getting ready with Diane to go out and celebrate with Gabe and others. Josh texted me and said he had to confess that he was sexual with another girl, his “best friend” Jane and that it only happened to fulfill their needs. I was fed up and angry and I didn’t reply and I was angry and done. So I didn’t speak to him
for four days but he would constantly call me and text me crying apologizing saying suicidal things and anything u can think of. I ignored him and I hung out with Gabe and we had sex.
