Should I forgive and forget?

MY girlfriend IS TELL ME TO SYAY OUT OF HER BUSINESS SHE AND I ARE HAVE PROBLEM. SHE KISS A GUY THAT WAS SHE WAS TALK TO ABOUT HER PROBLEM THAT WERE GOING ON BETWEEN US BUT IT WAS A EX-boyfriend
WE BEEN TOGETHER FOR 3 YEAR AND HAVE A KID . SHE SAY SHE SORRY FOR KISS HIM AND ASK ME TO FORGIVE AND FORGET SHE WANT TO WORK IT OUT I LOVE HER BUT I DON'T KNOW WHAT TO DO CAN SOMEHELP ME?

If she kissed him, then that sounds like a cheater to me...keep seeing the kid, but break it off with the cheater

everybody deserves a second chance and if you have a child you should think of your child. But once someone cheats on you, they are more than likely they would do it again. So if she does it again you should forgive & forget. You forgive her than you forget her...lolz
