How do you know your relationship is fixable or at the end of the road

My partner and I have hit a rough patch where it seems that I’m annoyed with him a lot.

Reasons for annoyance:

Him not standing up to his parents about taking covid seriously or defending me.

Being a bare minimum dad to our son. He puts video games before our kid and me. I can’t even get into why that bugs me. (Feels stupid)

I feel like the engagement was forced and all because I showed him a ring I liked on Amazon. Highly doubt he would’ve proposed soon if I hadn’t shown him. I just wanted to show him he didn’t need to pay an arm and a leg for one to give options.

I feel like his friends and family get more from him than me.

I feel lonely. I’m a stay at home mom with no friends to talk to.

I made a lot of sacrifices

Yes I’ve said all of this to him. He keeps asking what do I want him to change when he should be the one wanting to change.

Why is being in a relationship so difficult

My childhood friends don’t really make an effort to stay in contact with me. I’ve sent messages to keep up but I’m left on read(Facebook messenger). My college friend doesn’t talk to me ever since I had a kid I lost her number so I sent her my new one and nothing.

My plan was to join a mommy and me group after my son was born this year ,so I could make mom friends , but with covid around it has been put on hold.

I have talked to him about it. So we’ll see if there’s a change. I told him he has until the end of our lease to have some change if we are to stay together. If there’s no change then we part ways.
