Quarter life crisis

I’m aware this probably seems so immature.

I’m 25 and been with my partner since we were 18. We have a 2.5 year old.

I am feeling so miserable and I feel so guilty. He is not a bad person at all, he’s incredibly relaxed- like to a fault. I have sacrificed so so much for our son. He has a rubbish job with 0 ambition, can’t drive, cant be bothered to learn etc.

He is the least romantic person to exist but I do feel he genuinely loves me. He’d never cheat or leave me- partially because he’s so so comfortable and relaxed.

but why do I find myself being so bored?

I get scared he’s going to propose, not excited. I can’t imagine this being the extent of my romantic life but am I expecting too much? Am I the awkward one? We’ve never been sexually compatible- but again, it’s good sex but i don’t have the fire or passion and we never have.

I think im being selfish because we have a son and it’s not like im abused or anything but i just never want to be with my partner. I wish he would leave me… I have had that infatuated feeling before but never with him. I don’t know how we ended up together really- he used to treat me like crap and idk if I wanted to fix him or something?? Which I did the past 6 years have been fine.

I think we’d be great friends…

Sorry to ramble, has anyone else had these feelings before? What did u do?
