Should I stay with my girlfriend? She really wants to make things work, do you think we can?

And so, what are you feeling about all this?

Most Real Men (Who doesn't ignore their instincts and gut feelings to their protect relationship) would feel disgust.

All I can say is that this shows how poor your GF is when it comes to making decisions and I understand she cheated but why all the lies? Big RED Flag. The fact that she did not give up on her lies until the last moment shows the signs of a possible serial cheater. I think it's best to break it off with her before you get further hurt. You guys are going to have many more downfalls in your relationship and the same scenario is more likely to be repeated again.
