Ohhh Inga!! I am so sorry you have to go through this a week before the wedding! I agree with everything betsi said. He probably didn't have much choice in the matter, guys definitely rile each other up when there
together, and he's still young so he probably felt 'entitled' to it before he was married. Stupid? YES!! But I don't think he'd be marrying you if he wasn't ready for commitment.
How is he responding to your pain? Is he being comforting, is he assuring you that it meant nothing?
I'd say the most important thing at this point, since you can't change the past...is to work with what you've got. He needs to hear WHY you're so upset. And in a calm, discussion manner. And start it off with, I love you so
much, and I can't wait to marry you, but this b-party has really scared me. Then go into your feelings. Not just the jealousy part (which I would totally have too) but the part where it made you feel you can't trust him, where you feel like he
cheated on you, that you can't get it out of your head, that you think he did have a choice what to do with his hands, and that you felt lied too b/c you had told him that you wouldn't appreciate it if there were strippers there. Sometimes with
FI I also turn it around and say...how would you feel if you had these images in your head, or if you had to deal with this? Then he gets it. Anyway, after you tell him your feelings rationally.... LET HIM EXPLAIN.
Let him tell you that this isn't going to be something that happens regularly, that he's sorry for touching them (if he is) and that you're the one he's marrying b/c you're the one for him. I'm assuming he's not normally the type of guy
who frequents strip clubs since a) you are furious about it so i doubt he'd normally try and make it an issue and b) he went ALL OUT when he went.
And then Inga, you have to forgive him. See in his eyes that this was it... and then let it go.
On a side not, I have to say, I'm a bit peeved at your brother for telling you, sometimes it's just better we don't know. But it's also nice that...yes after some probing... that your FI came clean. Honesty is so important, even if
we don't want to hear it sometimes.
