My boyfriend and I don’t have sex anymore...

Our son will be one at the end of this month and we haven’t had sex in about 6 months... and I don’t even care that much. I mean it kinda bothers me but I just don’t care. I’m worried about him cheating though because he had a fairly high sex drive and he cheated on me in the first year of our relationship (we’ve been together 11 years)

Have any other ladies been on a long rut before and made it out just fine?
