Hello and thank you for advice and view this

This is how it all started

My girlfriend and I have been dating for awhile now. Until recently I began to change a lot. Mainly do to fact that my girlfriend lied about a lot of things. Anyway when I went to her Grandma house. I found her and her ex-boyfriend doing stuff(his hand were down her pants) in their grandma room. I got mad and punch him in the face a few times and kick him around and threw him outside. My girlfriend try to talk to me, but I wouldn't hear it and I left. When I got home she called me and try to tell me that some bull crap that if he let him do this one last time he would leave her alone. I don't really buy that story, but at same time I do love this girl and I don't know what to do. Help out

She cheated. She was being sexual with another man. If she truly cared about you she would have slapped him in the face. You said that she had lied to you before... what is to stop her from lying to you now? She is in deep water and she knows it so she is going to lie. Another thing is that is sounds like there is no trust in the relationship... so therefore you really don't have a relationship. I would say that you should let her go.

Yes... I'm with robertsqueen..

She is cheated.. in YOUR face... you caught her in the act, what more do you want... Move on, start a fresh... its almost guaranteed she will do it again!
She has no respect, even that she went and did this stuff in her grandma's room.

RUN RUN AWAY from this girl..

I'm with them both its not right for your girlfriend to do that to you. What to you ever do to her to deisrev that type of thing happen to you. I had to same promblem with my girlfriend she kissed a nother guy pissed me off out I gave her one more chance so it up to you to gave her a nother time around

Thank you. Don't worry I handle the problem with a swift backhand (SIKE) and breakup. Thank you guys

You leave and break up, please understand it is not something you use violence on, you could be in jail now for beating on this other guy, just walking away is what men do.

She cheated and if u get her another chance she just might do it again and no matter how much u love this girl you'll just end up hurt in the end of it all

OK if you do really care about her you need to sit her down and talk to her yes she cheated OK people do get around that if they care sit her down and talk to her ask her why she cheated and what can you do to keep her also you should say sry to that kid. You should really try to find a another way to take care of your problems then fighting but yes cheating bad but u said u cared about her so sit her down 1 on 1 no friends around and talk to her for real but u also said u broke up with her already guess u really dident like as much as you thought sry good luck my man

Sock it to her one last time real hard
Breakup follows

Run.

I am so sorry for you. But I do agree with the others. She cheated, it was wrong, and if she has lied to you before, who's to say that what she said to you about him wasn't a complete lie? I am really sorry that this happened, but the other thing is, if you really love her, you should let her go. Let her see what she is missing out on, let her feel lonely and guilty and unforgivable. What she did is unforgettable and unforgivable. Let her go and if she comes crawling back, don't let her ruin your life.

1 last time ? Are you ing kidding me!
Man she doesn't deserve you!!
