How do I go about having to live with an ex for a year?

r/

My now ex, (F-21) trapped me in a lease for a year with her and then left me (M-23) afterwards. I’ve done what I can towards moving on and loving myself, yet it’s not easy, we were friends for a total of 7 years and dated for 3 of them. I’ve done all I can towards my journey of self love, trying to work on my areas of weakness, and trying to move on, but it’s not easy.

I miss her greatly, and it hurts seeing that she’s completely moved on and suddenly feels nothing anymore. The reasons she says for not loving me anymore, is all smaller things, including my areas of weakness, that I knew were problems and were working towards slowly, that or they’re not fully my fault to an extent.

Im trying my best to be diplomatic and neutral, since we have to live together for a full year. Neither of us have friends or family we could stay with until the lease would pretty much be over. Yet staying here is hurting my growth. I finally take a step forwards towards trying to move on, and then she finds a way to toy with my emotions and I restart from the beginning.

We thankfully have a two bedroom apartment, so we’ve separated from each other, and are trying to mutually survive and just get by. Though with how she’s acted towards me and keeps toying with my emotions, I’m worried that if I say one thing she doesn’t like the rest of this year will become much more miserable.

What would be a good course of action to take towards protecting my mental health, to survive this next year?
