I have been dating this girl for 4 months, and we have just decided to become exclusive and have a relationship. I like her a lot, we have a lot of chemistry, and we get along really well.
We've been in a relationship for less than a week and have already hit a major snag. The other day she had a 'sleepover' with her male friend, Jack (name changed for privacy). She went to his house to watch a movie, and she had to work in his neighbourhood the next morning. They did not (according to her) sleep in the same bed. I consider myself pretty accommodating and progressive when it comes to opposite-sex friendships, but I draw the line at sleepovers.
Background 1: Her and Jack have been longtime friends. They have slept together and dated, but she tells me this was over 10 years ago. Her and Jack did not really speak for several years because Jack's girlfriend was not comfortable with their friendship. She has also had trouble with other boyfriends regarding her friendship with Jack. For this reason she is very sensitive about people being controlling about their friendship
Background 2: I am best friends with one of my ex-girlfriends, Jill. We dated for 10 years and it ended 3 years ago (it is not my most recent relationship). I am acutely aware that this is a sensitive spot for potential mates, and I am very careful with my behaviour to make girls I am dating (and Jill's boyfriend) comfortable with our friendship. For example, I would never plan to sleep at Jill's house...
Back to the story: I told Jill that I am ok with her being friends with Jack, but I am not comfortable with sleepovers. I told her that I need my partner to not do that (I probably should have worded it more to outline that I was uncomfortable, but we don't always choose the right words) She did not take it well, and told me it was "non-negotiable." She said that she does not view her male and female friends differently and does not modify her behaviour with friends when she is in a relationship. She tried to tell me that she wanted to deal with 'where the feeling was coming from' so that I wouldn't feel that way. I don't want a partner to change my feelings, I want her to respect them.
I'm at a loss as to what to do now. I feel really stressed because this is the first and only thing I have asked her to do to respect my feelings. If she will not compromise on this, will she compromise on anything? I feel like she is accusing me of being controlling, but I feel like asking her to not sleep at other guys' houses is a small and reasonable request. For me, having respected boundaries is an important part of a relationship. I feel like I am pretty relaxed and progressive when it comes to opposite-sex-friendship boundaries compared to other guys, and she may be taking advantage of this.
What my options are here? I can try to talk to her about it some more, but she seems pretty clear that she will not change for me. I can try to accept it and deal with it, but I know myself well enough to know that the next time this happens I will be very hurt and sad. And the closer I get to this girl, and the more committed we become, the more this will hurt me. Or, I can decide to not be in a relationship with someone who will not accept my boundaries, and who will not modify behaviour to protect our relationship.
I know that compromise is important in a relationship, but I don't know what kind of compromise can work here. I really like this girl, and want to make it work, but I don't know what to do. Does anyone have advice?
