Line between love and psychotic in Journal

It was around December of 2016 when I(23) went steady with my current boyfriend(21), we had been dating eachother since September of that year. We had been working together at the time and while it seemed odd at the moment, he always had his mother picking him up waiting at the door by our job; when she was around he would get tense and couldn’t even hug me goodbye or be close with me. Everything would soon come to full circle around March 2017 when this woman would later come to stalk my Facebook which was mostly private except for some pictures. When we started dating she started to harass him with “you don’t love me anymore” texts or “you don’t need your mommy” and for some reason he randomly bought her flowers one day to make her feel better even though there was nothing wrong with her… something a husband should do (which she has)
I don’t use my Facebook frequently so I don’t notice what is and isn’t there, but apparently when she was stalking mine I had some old pictures (with dates from 2015) with my ex still posted and this sent her on a rage. Me and my boyfriend were on chat on playstation, he left for dinner and left his microphone on so I heard her screaming the loudest rager. She was calling me a whore and a slut, that she didn’t want me in that house, that I was going to cheat on him… everything in the book. He defended me, he fought against her, I wasn’t allowed there anymore. But it didn’t stop there. She would take his keys to try and have him not see me, I in turn would just pick him up, she didn’t let me go to his college graduation or to his dinner after, his brother graduated high school and invited me to his graduation but she flipped and went crazy and said I couldn’t go. She threatened my boyfriend with throwing him out of the house, yelled about how he didn’t love her, raged about me cheating on him, and would not budge to me being around for even his birthday which he spent with me and my family this year due to all of her hate. During all this his father had nothing to do or say, he didn’t hate me and would wave hello if he saw me but he also didn’t do anything to tame his wife. Sometime around July I had fallen into an old habit I had from middle school where I used to be self harming. I had started burning myself and it wasn’t a good outlet but this time in my life was hard to go through. I no longer do that, it was a one time thing. When I had explained it to my boyfriend he took all the necessary steps to make me feel better and relieve the situation.
I never coaxed him or manipulated him, he’s consciously seen that his mother is wrong and that her behavior isn’t at all motherly more than it is unhealthy and gross.
What kind of good mom calls her son a pussy on the daily, a little bitch at the dinner table, and tells him he’ll amount to nothing?
The harassing texts she would send him Day and night, the obsessive gross behaviors of enmeshment that this lady had and still has today… I’m still scarred by all this and even today things still aren’t well. For the holidays his father finally put his foot down on the issue and made her accept me for the two dinners that mattered; Thanksgiving and Christmas. Awkward to say the least and very uncomfortable. Not one apology was spoken.
The same you don’t love me anymore at least twice a week.
The same you don’t need me anymore.
Now she even calls him sexy from time to time.
Invades personal space, goes through his drawers when he’s not around.
It’s like I’m fighting his mom for the spot of being his lover.
I wish he was a bad guy.
Least then I’d have a reason to leave.
