Everything sucks- need someone to calm me down

So I’ve been with my SO for 1 yr and 2 months.. recently I’ve felt disconnected from him and he’s been treating me differently but we always made promises to each other to never leave each other and now I feel obligated to stay with him! It’s stressing me out because I thought I loved Him and we are even ttc . I feel stuck and trapped

I talked to my ex a few days ago and it made me super happy until he told me he shouldn’t talk to me anymore because he’s 7 hrs away from me and he said he doesn’t think it would be a good idea WHICH IS SO UNDERSTANDABLE but I cried. I cried when he told me that. And I feel like I miss him (my ex) a lot.

I don’t know how to deal with any of this or how to break up with someone that I’m not sure I should break up with?
