I would tell him about it by ...
first: telling him you played truth or dare
second: tell him it got out of hand
third: that you kissed the other guys
forth: tell him you were pressured and you were against the idea in the first place
fifth: tell him that you hope he isnt mad and that you still like/love him
Yes, yes it does.
then your both screwed
is his kissing other girls or other guys?
she did but she was cheated on by Casey Aldridge and they were also engaged to each other.
NO
I think your question lacks information. For example, does your boyfriend and his ex have kids or any other reason for talking? Also, are you saying he has cheated on you with her?
You either have low self-esteem or he has cheated on you and you don't trust him.
It is clear he must have a cheating problem so you should leave him alone
She said he did when he was like 14-15 I think it was. but it was by kissing other girls in the schoolyard, not sleeping with anyone. Prior to that relationship his gf of 2 years cheated in him though with another guy.
No, it is not a good idea to meet the woman your boyfriend cheated with. It is your boyfriend who either instigated cheating or he was talked into dating by the other girl and he could have formed the word 'no' and this makes him 100% responsible for cheating on you. Let your boyfriend know you do not put up with cheating and refuse to share any boyfriend with another woman. If he doesn't take the hint then get rid of him.
If you have positive proof that your boyfriend has cheated on you and he is not responding then it is time to let him know that you don't share your boyfriends with other young women and kick his hide out the door!
Probably because your her boyfriend and she's supposed to be kissing you. Not some other girl. Is she bisexual or lesbian? If so, I understand why your jealous.
