You- divorced single mom of kids ages 3 to 16.
Him- guy you know from high school that had a crush on you back then BUT is still married, not sleeping with wife for almost 3 years (he claims they don't even share a bedroom anymore). Has 3 kids ages 5 years to 16 years (the 2 teens are her stepkids & know the marriage is over). Only reason he is still married is because they are trying to work down the marital debt & once that is down to a reasonable amount they will be filing for divorce.
He wants a sexual relationship with you but you (& possibly more) but you are hung up on the fact that he is still married. You had a man cheat on you before & know for a fact what that man said to his OW when he told her about you. You don't want to be THAT woman even though he says they are just putting on a front for the youngest.
So- question is would you? Keep in mind it has been awhile since you had sex.
