Starting to wonder if I should end my relationship...

Idk what to do anymore, it hurts to even think about doing it but I've been so unhappy lately. I thought this guy was the love of my life and idk if something in me changed or if something between us changed. I don't know how to make it better cause I don't want to leave, I still love him. But we never have sex, like ever, lke in the last three months we had sex once and fooled around probably twonor three times and we LIVE together. I'm in my mid 20's and he's in his late 30's neither of us should be THIS inactive in the bedroom. It makes me feel like something is wrong with me even though he insists it's him, he keeps saying he wants to have kids but it kinda takes sex to do that. And he spends like 60 hours a week at work and then like 10 at the gym, I feel like that's what is taking a toll on us but it's not like I can ask him to quit his job that supports both of us just for that. I feel stuck and beyond frustrated in the bedroom. I feel like I should just give up hope for things ever changing.
