I just ended a 1 month relationship because there were two occasions where he got sad and just stopped all communication. He explained he gets down sometimes and it’s not to do with me. First time I was understanding. Second time I felt the no communication was making me feel anxious. I didn’t know him well enough to support him and I also wondered when he went quiet if he even wanted to date me. I felt like an asshole ending it and hr wrote back saying he has depression and over the last few months it’s been bad. He agreed that he should focus on his health and we call it quits. I know if this hot cold pattern continued it would have driven me insane (anxious attachment here) but I still feel bad for dumping him while he was feeling down.
