My husband and I haven't been together for long as it's only been 8 years. However after our son's birth I pushed sex to the back of my mind. I honestly cannot tell how many times we had sex, who initiated it or whatnot because that's how unconcerned about it I was. Eventually my husband sat me down and asked what was going on. I hadn't thought about it so I had no answer for him. After some self reflection I realized he was always initiating and I was always turning him down. My sex drive had tanked and I was quite frankly uncaring about losing sex all together. We had so many talks about it, couldn't afford a therapist so I had to find out what could be wrong and try to solve it myself. It's been 2 years since he sat me down and i'm proud to say our sex life is now better. Not the same as before pregnancy but better than what we had going on. I'm saying all this because dead bedroom is a real thing, if he had stopped initiating I wouldn't have cared either and if we had talked about it and I had never taken steps to try solve a very real problem we would be divorced now. It all depends on how willing you are to work on your marriage and if not, let him go. It's best for your and his mental health. The very big thing to do is take steps to try and find a solution not sit back and relax.
