break up

my boyfriend said he would like to break up because i can’t give him enough space and he’s too depressed right now to care for another person :( i tried to tell him if he needs space we can be together and i’ll be sure to back off, but he said he can’t believe me right now because well it’s only been a day. he said i couldn’t possibly learn to let him have his space in a day. i didn’t mean to make him sad by not giving him space, we wouldn’t talk for days at a time, and i would get worried about him. he said he’s not ready or looking for a relationship now, but we both have agreed that we hope we can get back together soon once we figure ourselves out. i’m really sad because we got back together last night but woke up and said he’s really sorry but he just isn’t ready yet. I feel like i’m a terrible person and this is all my fault. I just want him to be happy and I care about him so much. we still are going to be best friends, just not more than that for now. we’ve been together for about 2 years. i don’t know how to get through this, he tells me he’ll be back but i’m scared he’s lying to me. how can I cope with this?
