can your girlfriend have a few guy friends to message only?

It isn't really a big deal, tbh. But I can understand why it would make you uncomfortable. As adults, it's important to recognise when we're being toxic towards our partners, and when our insecurities are hurting people.

If she says they're just friends, they're probably just friends. It's a different story if they've interacted with each other in suggestive ways, or if they're crossing boundaries that most people would be uncomfortable with.

It all comes down to whether or not you trust her, which is a you problem, not a her problem. You don't get to decide who your girlfriend talks to. If she's given you a reason to distrust her, talk to her about it. If not, it's really not your business. So yes, it's "ok"

It's controlling to tell someone who they can and can't be friends with.

If you sincerely feel like you can't trust her, maybe you're better off with someone else.
Otherwise you'll have to learn how to feel more secure in yourself.

Liking your friends photos is pretty normal friend behavior.

if shes gonna be a hoe, she will be a hoe. you cant control it by policing her, so dont think about it too much but dont be naive when you see very questionable behavior either

Is it ok? For your girlfriend to have friends? Yes.

Try not to put your insecurities on her. If you have no reason to doubt her, then try not to stress it.

As long they aren’t fucking her I think it should be just fine, do you have girls who are just friends?

I wouldn't trust anyone who said something was nothing

It's fine.
