<human>: I was told tonight by one of my close friends (who is also one of her close 

friends) that my girlfriend has cheated on her boyfriends before. It not 

have mattered to me if I hadn't just gotten out of a 2 year engagement 

recently with a girl who not only 

cheated on me but had my first child. My fiancé left me for that same 

man and gave me the wonderful gift of trust issues. I've never personally

 cheated and I cannot tell if I should be as incredibly bothered by this as I

 am now. Is it just me being crazy or do am I in the right to be upset 

about this?

Give me a shortened version of the text
<bot>: My ex fiancé/mother of my child gave me trust issues and now I don't know if I'm being crazy about being legitimately upset that my girlfriend used to cheat.
