My boyfriend and FB has feelings of doubt when it comes to our relationship. He has had them for a week now and it’s killing me. I worked my ass off this week to make him feel okay and try to be like when I was not in the worst period of my life, like I am now and when he fell in love with me. I worked so hard and tried to keep myself calm and all. I think I did a pretty good job. 
He seems to be only doubting it more now. He just told me this morning that he’s feeling depressed again and doesn’t want to make a decision right now. However, there is a “condition”. He told me, that when I lose control, he will leave me. Of course, this makes my stress level even higher than it already was and I feel extra miserable now. 
It got me thinking that, with everything I try for him, and me being there when he’s having a tough time, and he can’t even understand I don’t want to lose control and sometimes I can’t help it, he doesn’t even want to give me a normal chance. Do I break up with him? Before he breaks up with me? I feel like the chance he will stay with me is so small and I don’t want to live in this overwhelming sadness and fear for a month more and then be left alone anyway.. should I protect myself from this all and break up with him?
