Should I (22 M) break up with my girlfriend (22 F)?

Anonymous
My girlfriends parents still treat her like a teenager they monitor EVERYTHING and she still has to ask permission to go out with me ( I have a good relationship with them) and she’s never allowed to spend the night with me ( we can’t go on a weekend trips). You’re probably thinking my girlfriend and I should just get a place together we can’t afford it yet. Here’s the issue that pissed me off I really wanted to take my girlfriend on a nice weekend getaway and just enjoy each other ( we’re rarely intimate because of her parents and when we are we have to rush). Six months ago my girlfriend asked her parents if I can take her on a trip and they actually said YES so I’ve been planning and spending money on an air bnb / activities/ romantic stuff / spending money so my dogs can be boarded with our trainer. Every week we ask her parents if it’s still okay and they say yes. Well we were supposed to leave on our trip on Friday ( I was taking her to SD by the way I got a nice little Air bnb by the beach and I wanted to take her down to old town) last minute they told her she couldn’t go ( the very last minute a couple of hours before we were supposed to leave). I try to be understanding but I just couldn’t understand why her parents would say no last minute. My girlfriend and I were both looking forward to this trip I know it’s not her fault but Ill be honest I lost it and I never lose it but this was the tip of the iceberg. I haven’t answered any of my gfs calls or texts ( her friends and my friends have been trying to call me also) but I need time to cool off. I’m currently feeling sorry for myself in SD ( yes I still went because why not I won’t get my money back if I cancelled). This weekend I was planning to take her to my uncles jewelry business so she can give me an idea of what she wants when I pop the question ( I was planning to pop the question in October). What should of do?

This weekend will be spent drinking and working out / feeling sorry for myself.

I understand when we live at home we follow our parents rules but my parents understand that I’m a adult and the only rules they have are make good choices and be a contributing member of society.
