I'm lost! Please help!

Admins, please move post where it is most appropriate. I'm looking for advise!! Please I'm at a light and not moving but just hurting.

Here we go:

For every wife and girlfriend out there: you have one gift that men cherish most and that is that we are with you, and you are commuted to us by marriage or any other agreement. During good and during bad times. When you screw other men because of lust, attention, attraction or whatever your reason is you just got labeled as a census, a number, a fact in divorced and broken families, just another vagina that is worthless!!! Why I'm bringing this up? Because I've been there and I'm trying to control the damage that was done by my better half. She never considered the consequences and our children when she went to his hous in London Nigeria to get fucked no nothing for the children or husband. In my case it's acutely not true, my partner was considering everything and even had PDF charts on how not to get caught in their affair. I'm struggling with forgetting!! I have forgiven but I can't forget! I know I'm so close to find out the whole story and my partner does not share any details and that is the problem that drives me nuts!!! If I know them, I'll walk!! I don't want to walk but at the same time I don't want to suffer anymore! I love her but if I find out the entire truth she is homeless! I believe like most people say I married into a "slut". There were enough warning signs from the get go!! She has a girl by a married guy, she lied to me and told me the father died in a plane crash, she has two kids with me, even though only one lol ok'd like me, love l. She cheated (I don't know to what degree at her academy time in 2006. She cheated in the most awful way in 2011, she invited the guy (Johnson over as a guest to my house) not once, but more often. She invited him to dinner with other co-workers and he was always next to me or her. She told me one story and did something complete different behind my back! She exchanged porn pictures of herself with him, she spend countless hours on the chat room with him, she emails the most intimate pictures that we've had to show and seduce the guy so she can get a dick up her pussy! She was to go on a conference with me and sent me alone, so she could have freedom to ****. She tells that guy that she does not love him but another married guy and that all she does with the married guy is play because she does not want to break up a good marriage, remember, that guy is not me! She had the audacity to curse on me because I caught her cheating. She insisted for years that she never had physical contact with no other men, only for me to find out I was right and she was lying. She used the most intimate lingerie that I bought to impress the other guy, she tells me s couple of days later that sex with me is so different (how stupid am I for not catching up on this?). She told me she works overtime but leaves the house in full makeup and a big bag of lingerie. I don't know what to do? I'm at a stop light angry as hell wanting to find Johnson so bad. He knew all along she was married with me and we have three kids! After they (the other guys) had that pussy no one wanted anything to do with her and I had to comfort her when she was overflowing with tears of a broken heart or being hurt because the guy called her a whore!!! Where do I go from here??? Do I continue? It's been 3-4years now. But it feels though as if it was yesterday!
