As someone who has had an ex cheat on me I take it very personally when someone calls into question what I did to make ex cheat. He was/is a person with no morals, a money grabbing, lying, cheating, violent, evil twunt who'll prolly be spreading disgusting diseases around the women who do sleep with him.
I have a job, so couldn't have been my boring conversation , I also cooked three course meals in the evening (every freaking evening), made him hot breakfasts everyday, packed lunches for him, took care of his children, and kept a pretty near immaculate house, he never contributed to anything, I helped him reach the position he is in professionally etc.
I do blame the other woman for knowingly entering into a relationship with a man who she knew was married and had children, I also am very grateful to the OW, as she's the reason he is no longer in my life, I'm pretty sure she has got exactly what she deserves, ex!
Oh ex's reason for being a prick was that apparently I am ugly.... however, as I've not been short of offers since ex has left, and I'm not even looking, I'd say ex's assessment on my looks was a little incorrect.
This is a forum with mothers, most in relationship, of course it's going to get personal when people brag about their infidelity with married men/women. Read the relationship section and see just how gut wrenchingly painful it is for the wives and children stranded in the mess created by unfaithful spouses.
Sure grown people should be allowed to screw whomsoever they wish, equally partners of these grown people should be allowed to know they are not the only partners in these relationships and make their own informed decisions as to whether they'd like to be the household drudge of these people. Because really imo, if you screw him, you also wash his dirty socks!
OP whatever you do, lying to your children about their parentage is utterly hideous, and it's not like their fake father is someone to look up to!
