My wife and I have been dating for 5 years and will be married for 1 come May. We used to live in Cali, now in Oregon. When we moved here she made some friends. 2 out going girls who I like as friends. One is Bi and open about it. My wife, gf at the time, got more open with be sexual after hanging out with them. I like that . Wife and I would joke about 3somes, my wife being a lez.. Since she was real good friends with these two. It led us to talk about her kissing a woman, sexing a woman, etc. You know.. A guy's every dream to have his wife bring another woman home. I never thought it would happen. My wife isn't really like it. I just give her shit for having a bi friend. An old neighbor of ours, Her, her friend and my wife have gone out a few times. I know the 'her friend' not that well. Meet her 3 times. Real cool, down to earth woman. We all go out last night, Old neighbor, her friend, wife and I. Bar hoping, getting shitty. We close the club down. On the way home, I drop the two off. Wife and I heading home. She tells me she kissed 'her friend'. I say OK. Wife ask if it turns me on. I said.. Not really. I see 'her friend' more as a friend, not really attracted to her. My wife then asked me, is that cheating? I said depends on who you ask. I really didn't think my wife would ever do that. I proceed to tell her how she is different when she is drunk. More open with friends and I don't care for it(don't get me wrong, got to have a good time with friends, but she will do/act/say more things when drunk than she ever would sober). She got mad at me last night for the way I responded to the situation. I was a little mad. My wife out dancing, kissing this girl.. Cut and dry, that is border line on the cheating/starting to cheat side. Question is.. How should I feel? Did I think wrong? I would have never thought she would kiss the 'her friend'. I am not sure how i would have reacted if it was her bi friend.. But I wouldn't have been as surprised.
