Realizing im not the one

My partner and i have been together over 4 years. We have a 2 year old and now a 2 month old. We were unhappy for a while and we never really got better..we're good parents together though. I feel like he loves more than i might love him.

Theres been some things that have happened that have progressively made me lose feelings. His love language is physical touch and mine is by acts of service ie being a sahm. I also have been feeling for a while i could be lesbian, and he has also expressed to me he is scared of this because i dont like to be intimate anymore.

I also have been dealing horribly with my ppd and other mental health issues and havent been treating him happily some of the time and i recognize this. He broke down the other day saying he feels like he cant express his emotions, feels like hes walking on eggshells around me, and i know he sometimes wont even ask me things because hes scared ill get upset.

I feel like it would be good for us to split but he is the one who works and pays for everything..the apartment, food, bills, etc. Where would i move out to? We wouldn't have issues with coparenting or babysitting, we have 2 great grandmas..i cant get in with a therapist or anyone right now, the referral place called me saying they have no availability rn. 😞

He wants to work on us but asked me sincerely if its worth it. He doesn't think i appreciate him enough when i know i do but obviously am bad at being someones partner. We talk alot about how i have never been single and on my own, so i dont know how to be happy alone. I feel lonely alot. I dont have a single friend besides him.
