Don’t enjoy sex

I’ve been with my partner for 2 years. We used to have amazing sex.

Things have been rocky with us but we got back on track and dec was better than ever.

The last month or so I just don’t enjoy sex, I don’t want it, he pests me for it and it just feels like a chore.

Does this mean he isn’t the one for me? Something we can work on? Will my want and urge and need for sex come back? Will I ever enjoy it again?
