Hi everyone,
This is my first post so please reply.

Ok here goes... A year ago I found out my wife was cheating on me. I had been dating her for 8 years and married for one, we had just had our first child and just bought our first house, when she began cheating (physically)
My wife is the girl next door type, very innocent, always puts everyone else first, and very sensitive. Or so I thought, It turns out she had been lying to me our whole relationship, first about how many guys she had been with and teh specifics. Basically she has never said no to any guy who wanted to have sex with her, even if she didn't find them attractive. Shhe was faithful to me until her father passed away and she put on a lot of weight. She became depressed and begane chatting online then meeting guys. Fortunately or maybe not at this point it didn't become physical and I almost caught her so she backed off. She continued chatting and having cybersex etc, until right before our honeymoon (while 5 months pregnant) she met a guy she had been talking to for years (who previously said she was too fat, but now said he would hook up with her cuz she lost weight for our wedding) She met him and they kissed. Fast forward a year we have our son and she is still talking to the guy. They decide to meet at her work and have sex, she meets him and a few other guys over the next few months. During this time she goes out of her way to have sex and even give head (which she hates doing)and yet I sit at homeliterally sexually deprived.I catch her and she tries to lie and I drag it out of her, turns out she is like a pathological liar. She tells me it was like she was someone else and she felt like she was out of control and so sexy, etc.. I tell her I want a divorce and she taks suicide and ends up in a hospital where she is diagnosed Bipolar. She swears she will never cheat again her doctors tell me she was truly out of control, I want to forgive her and I have been trying but it's been a year and I just can't. I think the reason this is hard for me is I have questions.
So question 1. Could she be hypersual but not for me? Literally I had to beg for a quickie while she was spending hours with men who she says were not very attractive. (I am a good looking guy) Even though she swears sex with me is the best she has ever had and I know its good. (I understand forbidden sex, provides a rush in it self)IS that normal with hypersexuality or is she lying?
Question 2. Can I truly believe she will never do it again and she feels as disgusted by it as she says? ( I have been watching like a hawk and have key loggers on all our computers. She has been good so far)
Question 3. Is this really Bipolar and hypersexuality? (She also was on a nasty spending spree during this time and binge eating)
Any help is greatly appreciated. I wanna save my marriage and I wanna believe she can be who I thought she was.
