I suggested that he not go to the gym for now because he was always talking abt how if he hit the gym & got thinner and fitter, he'd be sexier & I'd like his body. I just didn't want to encourage him to change his appearance just because he thinks it'll make him sexier. It's kinda like encouraging someone to get a boob job because they think it'll make them look better & make their partner like them more. I didn't want to encourage his unhealthy feelings towards his own appearance & wanted him to know I didn't need him to change to find him sexy - I always do.
Also, I suggested that he try doing a double degree because it helped my dad have a firm footing while he worked on his photography career. We are not well-off financially so I thought it'll help fund his photography career until it takes off (like it or not, it takes time for talent to reach wider audiences in art - it has nothing to do with his talent). We talked abt this when we were discussing our options - which obviously means he wanted my input.

And if I was intruding too much, the fact remains that I didn't force him into anything. I made suggestions & he could have turned them down.

He was very angry that I talked to my old friends again (he says I shouldn't be able to forgive them for calling him a jerk during a previous fight). My friends apologized & I haven't talked to them for more than 6 months. I decided to let the fight go.
I think maybe he was angry because he was scared that they would convince me to forget abt him - he kept repeating that I shouldn't just believe everything they tell me & that I should have some faith in him.
He says he can't forgive me over our past problems. These problems are small & are not the kinda stuff people would break up over. He says he truly has these issues & that he isn't just leaving cause he lost interest in me. He finally admitted that I'm not the only reason for how he feels & that he does have some emotional issues.
He said that if someday he is able to trust me & feel no resentment towards me, he'll come back. He was only talking abt himself & didn't mention how he's been hurting me at all. While he did say that he doesn't blame me anymore (for the past few months he was insisting that I was the sole reason for his despair - today he said he said that because he was angry), he also says things like "I'll come back if I think you won't treat me badly again"
What do I do? Do you think he truly has issues or that he's just not into me?
Is it a good idea to be with him again if he does come back?
How do i help myself tackle this sitaution?
