The worst thing to do is sleep with the married man as once the adultery is official, the dynamic of the relationship drastically changes.
The other woman must think about herself and whether or not she will truly be happy with settling for being on the side. However, whether she settles for what he is giving her or not, nothing will fix the fact that he is not happy in his marriage and he will step out on his wife regardless. My dreams consist of love, laughter, and living life to its fullest.
If she expresses it, he already has his reasoning – 1) she knew he was married, and 2) he never said he was leaving his wife.
Sure there are a few people who actually leave their wives when they have met their “soul mate”. Although he gets to the point where he is saying he loves the side chick, he is usually more in love with his kids.
After they meet and exchange conversation, he realizes what he has been missing at home and decides to pursue his happiness with her on the side.
However, filling the void may backfire on him, as the relationship may escalate from occasional lunches during work hours or early dinners disguised as “working late”, to the more intimate texting and instant messages all night long.
