Hanging out alone with the opposite sex?

Is it appropriate for your boyfriend/husband to hangout late at night with a girl (even if it is a friend)?

I’ve been struggling to see how that could be appropriate. For example, your husband/boyfriend going to see a midnight movie with a girl that is his friend….does that sound okay to you?

If no, please explain.

If yes, please explain.

I don’t want to be controlling of my bf as I would want freedom to hang with any of my guy friends without worry what my bf would think…however I would never just hangout ALONE with my guy friend late at night…and if I was thinking of doing so, I’d ask my bf to tag along. Something my bf didn’t do when he mentioned he’d go out late alone with his gal friend.

Honestly I can understand the jealously I feel but insecure is something I don’t feel. I’m confident with myself. I just feel like things such as this is common sense on things you do and don’t do when you’re in a relationship…I want to express how I feel but also communicate how I am okay with him having female friends but I think there should be boundaries…but I’m just nervous and idk how to get that across!

Thoughts?
