Age is just a number in Life is beautiful

I should know better because I know a lot of cases about age being just a number. But in reality, it feels like I don´t know anything.
For some reasons, I don´t have a lot of friends around me; my bests are far away, like my family, and it has been a hard year trying to make new friendships. Even though at my age finding new people to talk to is easy, friends are not born from one day to another, and I´m already used to this situation… I met people, we have a blast, but we never stick together long enough to be close to each other. It has been like that for so long, that I actually started believing I would be alone for a long, long, time. But life has others plans.
I met someone, we talk a lot, we have common interests, common hobbies. He is nice and, so far, sincere with me, and even though we are not breaking any rules, not even doing anything close to dating, I can´t deny I have some strong feelings for him. And then the question pops, the answer comes, my heart is sad.
He is 5 years younger than me, he says “I would like for you to be younger, but I really don´t care about that”. I´m fine… I´m ok.... Now, let´s be honest, I wasn´t ok. It doesn´t matter how mature you are, when something hits you, it does hurt. And I was hurt. I never cared a lot about age, I have my limits, of course, but it still hurts. I said I was sad, he apologized, and I replied “you shouldn´t be sorry” because he is no one to blame for the truth. The truth is the truth, the reality is the reality. And my reality runs like this: I´m older, I like him, I´m hurt and I feel like giving up on everything but… it doesn´t mean I will. I reached the moment of my life where I don´t want to grow anymore. I would like to be younger, yes, but nobody knows how to do that.
He is a nice person, a nice guy.
Truth hurt me, but it´s fine.
I will get better, I´ll end up accepting reality and move one. My opinion about him will not change: he is an amazing person. I´m a little older but.... who cares :3
