My ex broke up with me last week and wouldn't talk to me about why, he said he was sorting something out and needed time, but was willing to be friends, message and maybe get back together after. Due to several reasons (anxiety included) I freaked out and sent him quite a lot of messages and freaked him out (I think) and so he stopped messaging even normally. I then messaged him two days ago asking if he was ok, he said yes but was sorting himself out and still needed space. Meanwhile I've heard several other versions of why he broke up with me from mutual friends, as well as he doesn't actually want to be friends/get back together. My mental and hence physical health has been all over the place the last week and I could just really do with closure, I don't particularly mind if he doesn't like me anymore as I can get over that, but not knowing and hearing all these versions are driving me insane. Should I message him asking for closure and if so how?
