Was it the right decision?

If he's amazing and the sweetest, why are you unhappy?

Because of how he sees me as someone who could be a psycho like his ex and will trap him into a relationship. And it makes me sad because I am not like that, but I just have that constant reminder of stuff he said . And how he seems me that low.

If you feel you need a break then you're not in the wrong

Thank you. The question is, am I suppose to avoid him or just be on my own?

You don't have to avoid him, just say that what he said or his actions upset you and you don't feel right in yourself currently, you'd like some space to think. see if he makes an effort

I think he has his own stuff to sort out if he has said this stuff enough to upset you like it has.

Everyone has a certain amount of baggage but you clear the air. Maybe have the odd argument when you feel like they're treating you poorly because of it.

You can't heal this for him. That's the sucky part. You could be best gf in the world but it wouldn't change his mistrust unless he could process his stuff and actually apply his current experience.
