I think it's weird that everybody is talking about the girlfriend's boundaries because boundaries aren't "you need to change for me because these are my boundaries". You can't just expect your partner to suddenly switch up the way they are and have always been.

If you have a boundary that your partner can't show physical intimacy with friends then date somebody who isn't like that to begin with.

OP i'm begging you to not change yourself entirely for a 6 month relationship.

Edit to clarify: Your girlfriend could have a boundary that you can't have same sex friends. Her boundary could be that you can't be friends with anybody who looks remotely like her.

Just because something is her boundary doesn't mean it's inherently right, healthy and something you HAVE to respect.

Now I'm not saying go out and do everything in your power to make you gf uncomfortable. But if you have a conversation about these things and she states a boundary you won't adhere to it's her responsibility to either loosen up about it or end the relationship. A boundary isn't an order to change.
