In many (maybe most) cases setting deliberate boundaries is not necessary. But there is nothing inherently wrong with having friends of the opposite gender. Many couples have different philosophies on this, and many men on this site have different philosophies on it. Some say that if a woman has real interest in you, she will drop her male friends, but this is not necessarily so. I know many long standing, successful marriages where both spouses maintain close friendships with the opposite gender. Others would not tolerate this. Neither is necessarily right or wrong.
I maintain that couples need to work out what is acceptable among themselves. Many people are willing to adapt to the other person's point of view for the good of the relationship. But I reject the idea that a "good" woman will know the "right" thing to do (whatever that may be) by some form of mental telepathy, because not even all men will agree what the right thing is. Not all subjects are a matter of right and wrong, but a matter of preference. How you deal with friends of the opposite gender, and where exactly you draw the line is one of those things.
For example, is it appropriate to have a friend of the opposite gender on Facebook? Is it appropriate to text them? Is it okay to talk on the phone with them? Is it okay to invite them to a party you are throwing? Is it okay to have lunch with them in a group? Is it okay to have lunch with them on their own? Is it okay to go out for drinks with them? Is it okay if they flirt a bit? Is it okay if they hug? How about a friendly goodbye kiss? Look at Hollywood stars, they greet each other with a kiss all the time, married or not. Is it okay if they spend time at each other's house? Is it okay if they play a video game in the bedroom? Is it okay if they sleep together? Is it okay if they have sex?
Point is, the line must be drawn somewhere, but there is no morally right or wrong answer on where that line is. People will disagree on what in the above paragraph is inappropriate. Couples need to decide that among themselves, it isn't simply a matter of "a good woman will know".
This isn't an easy question to answer. No one wants to feel like they are paranoid and controlling.
I've started writing and then erased several different trains of thought at this point, haha. This is a hard subject to write about. The last thing I was going to say was that I don't mind superficial orbiting, like having guys on facebook, texting with them... but then my mind created an image of a girl sitting on a sofa texting some guy and as I was going to proceed to the other examples my mind asked me, why is she texting a guy? My gut answered it for me with a strong sense of aversion to that scenario before I could come up with any words to reply. And then I had to end that train of thought too.
I was going to finish with it being about feeling whether you're the #1 man on her mind and your gut feels you can trust her. But again I thought back to her sitting on a sofa and texting, and I erased it. It's not something I reason about and conclude mentally, I just keep feeling the visceral sense that her sitting there texting other men is
wrong. I wouldn't be angry, I would simply disengage from her.
And now, I was going to end it with:
If she maintains personal, leisure relationships with other men, I feel it's them she should be in a relationship with, not me. But then my mind thought to her playing tennis with a man. This scenario didn't seem to trouble my gut very much. If they both like tennis and there's no one else in the area who wants to join them, why not? And after that I thought what if it was her and a man going swimming together, which immediately fired off that sense of error again as with the texting. I don't actually know why my gut reacted differently, but if I'm going to guess... swimming is obviously more sexual and unlike tennis, doesn't require another person to do, nor for that other person to be interested in swimming itself. Swimming would be more than simply a coincidental and conveniently shared hobby, and more explicitly a date activity.
The best prospective conclusion I think I can make right now is that at some point, a behavior gets sexual or personal enough that you start to question which man she
really feels for. But that still doesn't give a general definition for that point "philosophically". All I could do so far was get impressed on by my gut, and try to explain what I think it feels.
This is great... great post zekko.
