Was it wrong for this guy to break up with his girlfriend for these reasons?

[SugarRiceMan]

This one guy that I know just recently broke up with his girlfriend. The reasons why he broke up with his girlfriend is because he found out that she was getting naked and changing her clothes in front of her platonic male bestfriend (who she was living in the same apartment with), and she was sleeping in the same bed as him, and she was snuggling up with him when they watched TV together.

I know the guy's ex girlfriend and her bestfriend that she was living with, and I can tell you that she only thought of her male bestfriend as a brother and saw him as nothing sexual, so I think it was wrong of her boyfriend to break up with her for those reasons.

Its very common for girls to be that close and comfortable with other girls without anything being sexual, so shouldn't it also be common for straight girls to be that close and comfortable with boys without anything also being sexual?

The reason I'm asking this question is because I want to know what's and what's not ok for someone to do when in a relationship with someone.

There is no such thing as a girl having a male best friend. I can tell you without doubt that she have sex with that her male best friend. So the guy made the right decision by breaking up with her.

It's very inappropriate for a girl to go naked and dress up in front of another guy that isn't her boyfriend. If she is comfortable doing that in front of him, then she's probably having sex with him or will have no problem having sex with him. The guy wasn't wrong to breakup with her.

Would not be ok for me, so I would of ended the relationship also. Everyone is different and what they find acceptable is up to them.

But what if she gets dressed in the morning and shares a room with her platonic male bestfriend? There's no time for modesty in that situation, specially when they are adults, and its just a naked body in a completely innocent and non-sexual way.

You know you can have

friendships where seeing each other naked isn't a big deal. Seriously, being naked isn't always sexual.
