That's the healthiest kind of relationship.

If you or your partner are the sort of person who might cheat, then sure I guess. But I personally wouldn't want to be in a relationship where cheating was on the cards and we had to regulate our social lives to prevent it. I don't think that's healthy.

My husband and I have been in a rock solid relationship for over a decade, and we don't have any issues with opposite-sex friendships. It would be weird if we did because it would mean that we couldn't have any mutual friends and share a social life together as a couple. That seems really unnatural and unhealthy to me.

To add, depending on the context, this could also be a sign of controlling behavior. Policing who your partner is friends with is pretty classic controlling behavior, but insisting your partner not be friends with their preferred gender is also "normal" in certain circles. I don't think that's a healthy norm, but it is important context.

For instance, if someone's partner said they couldn't be friends with men/women, and then tried to create distance between them and their family, then I would advise them to leave that relationship immediately. That would be a dangerous situation.

Seems to me like such an act wouldn't be such a big deal if it wasn't usually surprising. I don't know what it would mean for it to be "on the cards".

Given the right circumstances, even an evidently unlikely scenario can become more plausible in the mind of the other, and you only ever have your own perspective to rely on in terms of what you think those scenarios or the predicate conditions are.

That doesn't mean it will happen or has happened or should be considered as a real possibility, but imo it does mean that if people could control for it, it wouldn't catch them off gaurd, which necessarily depends on it being unexpected.

And maybe any of those thoughts are indicative of being in a bad place relationship wise, it happens from time to time, it can be talked about, things aren't constant forever

I'm honestly surprised your comment isn't grey. Mind adding something to help others understand what you feel is obvious? I am left to assume why you think it is healthy and the only reason i can come up with is "boys and girls can't be trusted around each other" - and lack of trust and lack of contact doesn't feel like a basis for any kind of relationship.

I always wonder what these people think us bi people are supposed to do, have no friends and never leave the house?

In my experience, these types of people have given approximately zero minutes of thinking time to bi people. Or any other kind of person, for that matter. They know their perspective and that's all, and that's how they intend to keep it forever.

It really is not. It means there is jealousy, possession and lack of trust going on.

That your partner isn't allowed to associate with 50% of the people on the planet due to insecurity?
