I cheated on her.

I cheated on her, I talked to another girl for almost 2 months, she found a text on my phone, I want to kill myself, I feel I am going to lose her, I feel like she should take me back. I am mad because all these famous people do it all the time, like tiger woods, kobe bryant they lost a lot of money but there ladies stayed with them. I dont get either. This absolutely with out a doubt ruined my entire life.
