To be fair a lot of marriages (if what my friends tell me is true!) do lack intimacy. In fact. based on what I have heard, which of course may not be representative of the wider picture, more lack intimacy than not.
Speaking purely from personal experience, my own was lacking in intimacy for four years (at least) until I filed for divorce. I actively encouraged my soon to be ex husband to find another woman. Which he did! It got him off my back and meant I could file for divorce without completely shredding his ego.
Having said all that, I totally agree that married men (in particular) will spin all kinds of lies. One of my friends at one stage was seeing an attached man (never got married) with four children who was a serial philanderer. The friend was under some kind of delusion that she would be the special woman that he would leave his partner for. She even believed him when he persuaded her that they didn't need to use condoms because he always did with his partner!
I mean, how naive can you be! I suppose the idea being that she was 'special' so they could have unprotected sex. I couldn't believe she could be so naive. Also, who wants to hear that your lover is having sex with someone else? I think I would rather they lied about it. But there you go.
Totally agree with others who say you should play him at his own game and date other people. Just put him on the back burner. Don't start dreaming that he will leave his wife and you will walk happily into the sunset. That seldom happens as the pressure is too great and there are hurt feelings all around.
Get busy with your life. Date other people and have fun. People tend to want what they can't have. I was ardently pursued by a few men when I was married but since separated they seem to have melted away!
A fantasy is so much easier than a reality.
I think one of the biggest relationships killers is 'all or nothing' thinking. This can apply to any situation really. The more you try to get something your your exclusive self, the more that other person or persons evade you. It's like magnets - they attract and repel equally.
Take a step back from the drama triangle. The truth is, that if your lover really wanted to leave his relationship he would. Not necessarily (hopefully) for you but for HIM.
Good luck. Who said relationships were easy.
Sigh!
