M23 distancing himself from f23 what should I be doing?

TL;DR Me f 23 and boyfriend m 23 have been together for almost 6 months now and have had a really good relationship so far it started out as a fling but the more we hung out and got to know one another we grew feelings and decided to be in a relationship (his choose) as he wasnt sure if he wanted to be in another relationship.

A couple months in he started distancing himself which I noticed and when I asked about it as I just noticed he wasnt being himself and struggling with his mental health he broke it off with me and telling me he didnt love me.

He contacted me again and apologised and told me that he was struggling at the time and didnt think he deserved what I do for him and my emotions he told me how much he had regretted his decision and wanted me back.

I forgave him and ended up having a long talk about it and since then everything was fine until he fell into another episode but was still talking to me kinda normally until I asked him if we could call as I wanted to just see if he was okay and doing well he assured me that me and him was fine and I shouldnt worry but he then distanced himself.

we ended up calling again and speaking a bit more and he told me he was just busy and tired and struggling as he doesn’t know what he wants I brought up having some time to ourselves but not calling it off as ive also been struggling with my own mental health for the past couple of weeks but now we haven’t spoke in a few days and I do miss him but im not sure where im supposed to go from here.?

I do want to make it work with him but I dont know what im supposed to do from here can anybody help?
