she lied but says she didn't cheat-long post-Sorry.?

I know what i know and i think she did cheat.but she swears up and down she didn't .i caught her lying.
Well we've been separated for a year now.i've been away for reasons out of my hands and we are in a long distance relationship while i'm away and she had out 2 kids with her. and i will be goin home in 2 months give or take.
i've had this feeling something was going on and confronted her about it, she said no i love you and i would never do this to you and i'm being paranoid. I told her that we'll see as i will find out somehow.
shortly after she said she said she going to her gamma's house so agreed that we would talk later that night. tried to get a hold of her all night and not a word from her and she wouldn't answer her phone. I got worried and thought something has happened. i called her mother in the morning i heard my kids in the back ground she seemed nervous ,i played it cool with her but i already knew something was up talked to her normal and finally i asked about my wife she said she's had stuff to do n she should be with her dad by now. so i call my father in law n he said that no she's not with him and he doesn't know where she is. at the point i knew what was going on.She didn't spend the night at home with the kids and her mom watched the kids over night and lied for her.
Any way i kept calling her phone ,it was noon when she answer she was in a rush and sounded like she just woke up. said she's on her way and she was at the store. I said no u r lying to me and call me when u r ready to tell the truth.
I was so angry,hurt and heart broken for i loved this woman and really trusted her but i also knew that the long distance thing was a big factor.. But i couldn't help it and my anger was clear. but she kept saying she didn't cheat on me and she went out then to a friend's house for drinks.
I don't believe her .i asked this friend he said she came for a few drinks n left early n that's all he knows.She said he's just covering for her cause she told him about our fight.. well i believed him, now all her family is mad at me for treating her bad.lool. her brother sent me a msg tellin me that we gonna have problems if i don't change the way i treat her and that she didn't cheat on me. The day after his gf posted on facebook about her ex and how her friends didn't want to be the one to tell her he was cheating on her- odd timing,right?- few days later a very close friend posted that if u have a bad feeling it means something is wrong .I don't know if i'm paranoid or not but the timeing for these posts was strange, also for them 2 girls to post stuff like this is not them at all. felt like they are trying to tell me something. and in the middle of this fighting i was reminded to all the shitty things i don't to her and was even threatening by taking my kids away if thought of leaving here.
We are talking again now since i forgave her for lying . but i can't believe she didn't cheat on me that night or maybe other times .
i love my kids and i don't want to hurt them. i really want to divorce her since i can't trust her any more and to be honest i feel different about her after this.
I don't know what to do.????????
