my girlfriend cheated on me while in jail for a month

Hi,
I guess I just wanted a little advice and help. So, my girlfriend went to jail recently. She was in only a month. While sge was in, I took care of everything for her. I took care of her dog, her debts etc..
So, why she's in there she calls but not much and when she does call it's not for long. I find put from one of our mutual friends that she believes me to be cheating because I missed a couple calls while asleep early in the morning. Also, I missed her court date. However, I was very sick on the same day as her court date and everyone even explained this to her. I was in bad f'n shape. I got so sick. I couldn't move without vomiting. Anyways, that is why I wasn't able to go to her court date. So, of course this was one of the excuses she used,combined with I didn't pick up every single time she called...black bla black! Really, it was just a damn excuse for her to be a skeeezy scAgette!!! So, long story short she cheated on me in jail and our friend told me because she felt bad for me and because my gf Kora basically bragged about cheating. Claiming I was sleeping with someone who's just a friend. Which I wasnt.. Again she just needed another reason to be a ho. So ya she slept with this chicken who was not only a crazy fugly ho who stabbed soneone but who was also her psycho celibate. She slept with her 4 times, 4 times! Lied through her teeth to me over the phone when I confronted her. Then the metal friend she told all of this to, got on and went off on her for lieing to ne and calling her a liar. I could tell Kora was lieing by the shakeness in her voice and the stuttering. I asked her to be truthful just be real and she lied. Zoooom ahead, I let her stay in jail instead of paying the 660 to bail her cheating ass out. But one day not so long ago she shows up at my door. Remember, I had been watching her little dog Bubba for a month. He had already gotten attached to me and didn't want **** to do with her..haha! Just had to through that in. Anyways, she's crying and sa,ing she had to do it or she would have gotten beat up. How she had no other choice because she would have gotten beat up fir getting her braids and having no way to say for them. Which is also messed up because I gave a good friend 140.00 to put on her books n he lied and said he put it on her books when in fact he took the money to a slap house and gambled it away and bought Fentnyl. Piece of ****!!! So, that was her first excuse that she did it because this girl was friends with the girl who braided her hair. Then the excuse was because she had no money on her books for snacks and hygiene. So, I said to her, so u basically broke my heart for treats and deodorant??? Bitch! Think of how lame that sounds. I told her she did it because she wanted to . Bottom line! She didn't even care about how i might feel. If I found out. She did what she wanted because she's a selfish little ****! Then today she admitted that it was because the firl was looney tones and she was her cell mate and she felt she had absolutely no choice. So, the girl raped u. I said??! No, she replied.. I just know she was crazy and plus she helped me out. Helped u with what?? Cheat??!! Keep in mind this broad is white trash and ugly as can be. Also, tried to murder a mom in a park. My gf claims it was this, then it was that. She can't even get her F&*$#*G LIES straight. I'm so annoyed with her. I can't even look at her. She tries to minimalize it all. It's bullshit because I'm hurt. I've never cheated on her or anyone for that matter. Trust and believe I damn well could. So after all that, today my neighbor comes to the door all upset, wanting to speak to her . I thought it strange and all. He was pissed and wanted to speak to her alone. I invited him in and he rudely told me no. He needed to talk to her asap. Well, automatically I think she's cheating. Long story short. She promised to have sex with him for being able to use his car from time to time. She didn't follow through yet. She was kinda leading him on so he was mad. Then she denys it all. My other neighbor Raven explained that he'd told her they were gunna messages around and she flaked. She disappeared to his house fir awhile today but still didn't sleep with him I guess. So he just texted me all of her foul ass text. They all talk about 3 songs and how she'll do him etc etc..
I just want to run her ass over with a dump truck and back over her again. I'm so heartbroken.. I could never really do that. I'm just venting.
So, please any advice u can give, I'll dearly appreciate.
Sorry for the typos and what not. I'm tired and my back aches. Anyways advice ????? Please help! Any would be greatly appreciated! Thank u so much
