What if this happen to you?

Well i have been going out with this girl for over a year and she kiss this boy on the cheeck but nothing else..
I want to trust here I used to trust her. I know she has not done any thing else. I have known her for along time...
IT makes me sad that she would just go up to a boy and kiss him.
What would you say or do?

did you confronted her? nwy if she really loves you, probably even if she kiss the guy on lips, it wouldn't really matter as long as her heart says you are the one for her.. that kiss probably means nothing.. plus, she didn't do anything else.. trust me.. talk to her and forgive her if she didn't meant it.. that's what love is all about.. trusting and forgiving~

well 1st of a kiss on the cheeck means nothing girls do that with friends and such it doenst mean anything at all .. maybe she knew teh guy and was juta asignof greeting i do that all teh time to girls and guys i know.To gilrs its not biggie but if un comfatable about it just tell her it makes u feel a lil jealous or ask her why she she did taht and all uve been daing a year thats a long time so im sure it was harmless and she ll understand ur asking.But iwouldnt get werked up over it ist not soemthing you should worry about or think will lead to nething else it truly is harmless.Well good luck hun
