try not to get angry here...
Why is her happiness with someone else bothering you?
THEY are divorced. NOT you. She paid her price for cheating. He left her. NOW she found someone else. Had she been married to same guy, your friend NOW, Do you think she would also post how much she loves him. Did you ever wonder that he IS a great second dad. He IS the love of her life. MOVE ON. Stop getting mad at her for being happy. You dont like her? you feel she did something wrong? You cant forgive her for hurting your friend? They DONT associate. Shes asking you out cause she has not a clue that you hate her actions. You never told her this. She assumes shes still friends with you. She has no ideal her FACEBOOK quotes are bugging you. Why? CAUSE they are not meant for C. M. They are meant for everyone that cares two farts about it. You just dont like reading it.
Her kids obviously like him, so no big deal, if you think he is yucky, then go out with them and find out for yourself, instead of judging him for something he might not have had anything to really do with.
Shes not friends with DAD on FB right... so WHO CARES.
One thing I am seeing in all these posts is, She cheated, that makes her a BAD person... sick, disgusting Cheater, cheaty cheaterton... so is cheating on your husband worse or better than cheating on your taxes? Lying to the law, lying to your kids, lying to god, cheating on god, cheating on your diet... when do we make that list where one digression is worse than the other. WHO are we to judge that? Everyone Cheats and Lies in someone way. So then everyone's character stinks. She got caught. Wait for a few years, your going to find something out about dad friend your not going to like. I bet ya a hundred bucks. It could be far worse than said ex wife's cheating. Why drag the transgressions on and on. Be up front.
ADDITIONAL: just to make it clear, I am a divorced woman. I left my husband for cheating. My husband was sleeping with a woman who was still married, and her husband was dying in a hospital bed in their bedroom above them, while they were doing the deed. Yeah... had some problems with that after her adult teen SON caught them and told me about it. My boyfriend of 5 years cheated on me with a 14 year old. I am re-married with kids. I have since forgiven my husband and boyfriend for cheating, because when they did that , they lost the best thing they had. ME. They learn it later on. My boyfriend of 5 years married his cheater, and now is divorced again and is living on the streets. My ex-husband was dumped by cheater ON FB, where I got to see it and laughed my butt off.
