For backstory, We both met in college last year, and immediately hit it off. He is an amazing person with an incredible sense of humor and a great personality. Even before we started dating, we would sneak out just to hang out without our other friends and it was always really fun. He and i connected quite a lot, in everything ranging from music to food.
We started dating around a few months ago. Everything was going good, until i honestly started feeling jealous of a few behaviours of his, which i communicated once and he stopped. But because of my request, he started becoming more reserved. Since i asked for monogomy, his friends started disliking me for it and subsequently stopped talking to him as much, since he “isn’t fun” anymore.
I have felt guilty, but he says not to worry about it. It has bugged me quite a bit. That and his previous habits (of which i used to still hear stories of) were always at the back of my mind. Now the thing is, he comes from a broken family and being a caretaker, he always tries to handle every fight and every issue that comes up. It started taking a toll on him around 2 months ago. Our perfect relationship started deteriorating as he stopped sharing things with me, and i started feeling like i was talking to a wall. He started insisting that i didn't trust him, because of my reluctance to tell him my issues. This all turned into a big fight where we both said hurtful things.
We worked it out, and started getting back in our normal routine. He mentioned, that the “peace” he once felt with me, has been lost. He still insists that he loves me and wants to be with me, and i want to be with him too, but after all these things, he has stopped sharing saying its worthless. He started having self esteem issues, to which he always seems disgusted when i tell him how attracted i am to him. We still have fun moments, loving moments when the issues are not at a forefront but he Just starts distancing himself in these situations completely. I want to be better and i want to support him to the best of my abilities, but i suck in this department. I should know what my boyfriend would need to feel better but i seem to figure out what it can be. I have asked him, and he says he doesn't know. I atleast want to do something so he doesn’t spiral. I want him to be better and I’m willing to do whatever it takes.
Any advice on how i could support him better?
I am working on myself so I’m not a bad person to him but its not enough.
TL;DR: Need help in supporting my boyfriend better emotionally.
