Advice for the new girl.....

I was just thinking that I wish that I could talk to my ex's new girlfriend to warn her about what she is getting herself into with this guy. He may seem like a nice guy but she never knows what he could be doing behind her back. Believe me, he has cheated on me, lied to me so many times I can't count and snuck around behind my back. It is not like I would be trying to tell her stuff to break them up but I feel like woman to woman I would like to help her not go through the same stuff that I went through. He walked out on me I assume for her so he could do the exact same thing to her that he did to me. Throw her in the trash and not think twice about it. I just hope she realizes that she deserves better before it is too late and she ends up getting pregnant by him or something. You would think she would think why would I want to be with a guy who has 2 kids by 2 different women and is already in a relationship with me when he basically just got out of one? I hope she is smarter than me and doesn't waste years on him before it is too late to realize that you wasted all your time loving and giving your heart to him before he throws it in the trash and moves on to the next girl. I wish I could tell her all of this but she would probably think that I am bitter and all I want to do is break them up when all I really want to do is warn her because who would know better than the woman who spent over 2 years with him. He is not trust worthy at all. I feel like I would want to prevent her from going through the same thing that I went through but I know she is going to have to figure everything out on her own. I just hope she doesn't wait too late to figure him out. All I can say is good luck to her......
