just a couple of things
First a little disclamer. I haven’t read Bib’s tips regarding this subject so what I’m about to say might have been already said by him or by anyone else. Also, I’m not maried, not even close to it, so what I’m about to say is only empirical or from other person’s happenings.
What I think this shows is that your wives are taking you for granted. That is, they know you’re home, they know you’ll do this, they know you’ll do that. As this happens, the wife is starting to see you not as a husband who has sexual needs (like they do, they just don’t show it) but has a partner who shares the same home and some other things. What this shows is, of course, if you want to break that downward spiral is to break this image inside her head. And to do it you need to change your lifestyle a little.
She’s ignoring you. Sometimes even doing things that gets you pissed of at her attitudes. What you need to do is act like what she is seeing has you are, act like a partner and not a husband. Spend more time with you and /or your friends away from home. Talk to her briefly but not disrespectfully, always showing that if she’s ready for a serious conversation you’re ready too.
When that talk happens, don’t get pissed off, don’t get mad, just show her how you view what she has been doing, how she’s acting, her attitude towards you. Don’t talk about sex. Just ask her how she’d act if you acted the same way towards her.
I don’t know if anyone is going to use some of this, but please, I’m no therapist, what I’ve stated is from what I’ve read / heard about other similar cases. It might not work, and you probably won’t lose anything trying. On the other hand it might work, and I think it’ll be very good to surpass such “hard” times, don’t you?
Hope I’ve helped.
