Yeah I don't think he is seeing someone else. I am not and I am not having sex with someone else. I would say that after I became pregnant he got weird about me being a mom, and being a sexual being.
I didn't marry him thinking I could change him. When we got married we were still having regular, albeit mediocre, sex. The lack of communication comes in when I want to discuss this problem and he acts like it's not a problem. That is part of the problem!! lol.
Hey, this was exactly the problem with my ex-boyfriend. We were together for three years or so, living together for most of those years.
We were/are the best of friends, and our sex lives never matched up.
Because I gained weight in that relationship (as did he), I thought it was a weight thing and I tried to lose weight, we went vegetarian, I signed up at the gym, I tried to talk to him to find out why he didn't want to have sex with me as often, it kind of sounds like a lot of what you are going through.
He also didn't think it was a big deal. But it was a big deal to me.
At the end of the day, we broke up because we were great and awesome friends. We had a great time together, but the sexual and passionate side just didn't exist between us.
It wasn't my body, it wasn't his body, it wasn't stress or medication or anything else -- it was simply that we weren't matched in that way.
You are married to him and you need to talk to him -- you need to tell him it's an issue for you, even if he doesn't think it's a problem. And that you would like to go into counseling, especially because the two of you don't communicate very well.
Maybe his sex drive is low -- there are plenty of people out there who are comfortable having sex infrequently. But you not only need to find out what's going on in his mind and his body (if it's a physiological thing), but you also need to find out if this is going to be the way it is for the rest of your lives.
And you need to also consider what are YOUR options if nothing changes? Would you want to have an open marriage? How important is sex for you? Can you NOT resent him for not wanting more? Etc.
Jokingly my current boyfriend (who knows I'm on my weight-loss journey) said that if I lost weight, he'd have more sex with me. We'll see about that. I think we're both pretty satisfied with the frequency and amount we're getting.
