Infidelity Support Group
Any relationship in which one partner engages willfully in sexual relations with another outside of the partnership is considered to have experienced infidelity. This breach of trust is often traumatizing for the faithful partner as well as the relationship, and support is often needed to heal emotionally and to decide whether or not the relationship should continue after...
Seems like you know her history in any sense.
As well you didn't ask any questions so I assume you just want to hear a perspective.
You married someone who you know had some significant issues that would likely end up being a deal breaker.
Get some counseling to sort yourself out. It is pretty apparent that you have assertiveness issues from your story. This is the kind problem that can cause a repeat.
After I found out about my wife I realized that while she did hide who she really was, I really could have aimed a bit higher in terms of strength of character in a mate.
In your case there were some glaring signs that this wasn't going to work out.
I think it doesn't matter at all if her AP is a man or women. the act of cheating is there, she cheated, she has no remorse, she has no empathy, she doesn't understand the pain she caused, she lies about it, she risks ur health with STD's, and she did not cut all contact with AP, so the affair is still going on.
She may be bisexual however that's not an excuse to cheat, she is no different than most cheaters and if she's not remorsefull theres no use on trying to fix this relationship.
Take some distance from her and consider counseling for urself, being cheated on is pretty traumatizing.
wish you the best, follow ur guts, I think its telling you to run.
