Hi Op my first thought is similar lines of first poster.
My next reaction to your thread is be careful for what you wish for (,thinking the grass was ever going to be geeenner the other side of this deceitful affair.😕
Consider this,what makes you think a man who cheats on his wife, and I guess tells you stories how she doesn't understand him etc etc,
Would, could be a more genuine trustful partner with you then??
If he can tell lies so blantelly like that with his wife,
How do you know if he left his wife for you, he could be trustworthy with yourself with you etc etc.
His marriage, his wife may be shit,??
But if he is not happy he should either throw in towell in towell, quit or get marriage counselling..
Also some married men, just chase skirt outside marriage just purely cause they are very immature,needy and are just bored of vanilla ,want something bit different novelty factor,escapism,
Basically its horses for courses how do you know ex married lover wouldn't treat you the same as he does with wife if the situation was reversed then??
