First relationship

So I’m now 20 and have been dating my bf for ab five months but have been seeing each other for almost a year now.

When we were only friends in the beginning he talked ab his past relationships sometimes and how he genuinely thought he was gonna marry them and even asked one of their dads for permission to marry or whatever. They both ended it with him.

So Ik he dates to get married.

I’m just so new to all of this. He joking will propose randomly just like an innocent fun way like while we are cooking at his place he’ll get on one knee and make a joke.

Other times he’s in a serious mood and asks if I’ll stick around and be his wife someday and we talk lots ab a future together.

His parents even invited me to vacation w them in Hawaii at the end of summer.

I just know people, especially myself in the past, always say that most of the time first relationships NEVER work and it’s only for lessons and heartbreak.

I remember my friend who also had her first relationship recently and they talk ab their future too. It’s just a lot easier from an outsiders perspective but, Ik they aren’t going to get married. It’s just not happening now that they’ve almost called it quits and fight sm after almost a year together.

I just don’t want to get my hopes up but I don’t want to put myself and the relationship down so much in my head that I can’t even enjoy it... if that makes sense ??
