Hello!

I'm looking to hear people's thoughts on depression and relationships. I'm (30f) a bit stuck as to how to proceed right now in my relationship with my partner (31m). I thought maybe getting perspectives and advice from others might help.

We have been together for about a year, and he has been very open about his past struggles with depression and attempted suicide. He's worked very hard to get where he is today, is medicated, and his therapist recently told him she thinks he is ready to stop seeing her. He still has his ups and downs, days where he struggles and days where he doesn't, and I always try to support him through it how he needs, whether that is space or cuddles, or making him a snack, or taking or whatever he communicates he needs at that point in time.

Today he seemed a bit off, and I noticed it yesterday too. Eventually after a chat he told me that up until yesterday he could see his entire future, me, him, the dogs we own, a nice house, him working at a job he likes, etc. He told me that yesterday it just suddenly all disappeared. Like a light switch had been flicked in his head and he couldn't see anything in the future anymore, just him and blackness. I asked him, perhaps selfishly, if he saw me in his future and he said he didn't know. I asked him if he saw himself with someone else, he said no. He said he saw himself alone and nothing else. I asked if he wanted me in his future (we had literally spent the last six months excitedly discussing having children, instigated by him each time), he said he didn't know. He said he wasn't certain of anything anymore and the future just looked black and he didn't know why. He explained it wasn't just me, it was everything in his life that was gone. He was very upset about this, then just kind of numb.

He is sleeping now, and I am feeling a bit stuck as to how to proceed. One part of me is saying 'don't stay with someone who has just explicitly told you they aren't certain about a future with you'. It feels silly to hold on to the relationship if he doesn't see it progressing. The other part of me is saying 'it's not about you, it's about something he is going through. Wait it out and help him.'

Ideally I'd like the second part of my brain to win because I love him and want to support him however I can if he's going through something big. Alternatively, if he is serious about not seeing me in his future, is it unfair to myself to spend the foreseeable future supporting him knowing he doesn't want me in his life and waiting until he has the courage to say it outright?

As someone who has never experienced depression, or been in a relationship with someone with depression, I'm hoping to get some thoughts off people on this sub. I'm very open to learning and growing, and hearing about the experiences of others. Obviously I know the best thing is to talk to him, and I will continue to do so, but I also don't want to push him when he's clearly going through something and not able to explain what's happening in his head. 

Thank you for taking the time to read.
