Is it possible to change it?

He said he likes me, but our relationship is only on a physical level..

We were dating for 3 weeks and first two were great.. but the 3rd one was strange.

Partly because of my weird unusual mood swings and stress. He also had lack of time and stress. But suddenly I’ve started to feel distance and I’ve started to ask what’s wrong and he always said everything’s alright... and it was. But on Saturday we had a little fight because I got sensitive and needed attention and he was pissed. I admit that my behavior was strange and I had a period on that day so might be because of that as well but anyways next day I decided to come and say sorry cause I felt like there’s some misunderstanding left.. he said everything’s fine and he understands. But half an hour later he said that yep it’s a problem so let’s break up...

A couple of days later I’ve tried to talk to him again and he said that he finds hard to be with me because we aren’t close enough on emotional level.. he likes me andfinds me attractive but I’m not open enough or something...

and I don’t get it.. I feel like there’s not enough time yet to become emotionally close yet. I need some time to open up and I had a hard week... I wish he could’ve understand me... I feel like everything could’ve be fine but one stressful week destroyed a good impression of me.. I feel like we just needed more time and it’s too soon to break up. I really like him..
