Bipolar 2 sudden break up

I’m a first timer and looking for any advice please. My boyfriend of 3 months received a bipolar 2 diagnosis and started on new medication about 5 weeks ago. About a week after his diagnosis he travelled overseas. Having recently returned he tells me he has lost his feelings for me and needs a break. Only then did he tell me he has bipolar 2.

Based on what I’ve read, I think he is in a low period (depressed) has lost interest in the relationship, he doesn’t know why and is pushing me away. He has also had the added stress of moving house this past week.

We agreed to space (I’m using this time to educate myself) but I’m not coping. I’ve told him I will support him but he doesn’t think it’s fair I wait around in case he ‘snaps out of it’, were his words.

Also worth mentioning, this is our second attempt at dating in 12 months. In hindsight I believe he broke up with me the first time while also in a depressed state. He wasn’t diagnosed at the time but all the symptoms and behaviours points to bipolar 2.

How much space do I give him (we haven’t seen each other for about 1.5 weeks now, minimal contact from him) and are sudden breakups common for those living with bipolar 2? I hope this isn’t the end for us.
