Is it normal my girlfriends parents won't let us have space

Gee, my whole generation got laid in our cars. I know cars today are quite a bit smaller, but with a little imagination, I'd think you could manage OK.

Her parents are fucked up... Kninda reminds me of my ex's parents. They used to be overprotective too. In front of them even a kiss means I get a dirty look from her parents.

Needless to say, that didn't stop me. We went out. We used to sneak into her place. We went to the beach together (She lied she was with lady friends)
However, in the end things fell apart. When it came down to her moving in to live with me, her parents were fully against it! And she listened to them. She had no willpower. No desire, no power to make a decision. We kept things going for another 6 months, but a relationship can't last when you are 2000km away from your girlfriend.

So, I moved on. Currently happily living (most of the time) at my girlfriend's place.

Here is my advice. If you really love this girl, continue the "fight". Try to get accepted. If things don't budge and seem impossible, maybe you should find another girlfriend with parents that will accept you. Cause even if you get married to that girl, do you want to have in-laws that hate you?

She's 20 and they won't let her out of the house unsupervised to see a guy? No, not normal.

It's not unusual for parents to be overprotective of their daughters, but this is excessive supervision for an adult child. Since you say she's not allowed to go on dates alone, you have one of two options: A)She can stand up to them (admittedly, this may not be wise if she's financially dependent on them), or B)You can try to tough it out until the summer is over and you can go back to your normal life with her.

Another possibility: since you are already living together during the school year, you could make it official and get an apartment together. Then you can spend as much alone time together as you like. But only do this if you are truly serious about each other, and both of you feel ready to take this step. Also, you can expect to get some pushback from her parents, so it's important for both of you to stay strong and present a united front.

See going away for a night isn't an option. They make her sister come with us to the movies. I'm not saying I just wanta get laid although it would be nice. I really just wanta spend time alone with her.

Go to a festival or a town far away and stay overnight. You're definitely of age so that's not a problem but I think it's cool that she has parents like that. I feel like they're too strict but at the same time, it means they are really looking out for her. You better use protection man.
