So I’m feeling lost in my relationship

I love him so so so much. And I know that in my head and my heart. But I feel like I’m constantly fighting with him and alway annoyed at him !

He’s no longer satisfied me sexually in ages.

We have sex but it’s like 2/3 mins he cums and that’s it. Also that only once a week if I’m lucky.

I really don’t know what to do I try to talk to him but don’t seem to be getting though to him...
