Have you ever had difficulty maintaining perspective in your younger relationships?

I’m 19 and in a relationship. My boyfriend is fantastic, and I have no desire to leave him, though I know he’s not “the one,” my “soulmate,” etc. I’m not in love with him to the point where I can’t envision myself having a future with anyone else. But to me, that doesn’t mean the relationship is a waste of time. I am enjoying myself with him. I’m young and I don’t need to find my soulmate just yet. At the same time, I kinda just want to fast-forward to that security. I know a couple my age that broke up because the guy felt like they were already married, things were too heavy, and he didn’t want that at this point in his life. I guess he wanted time to be young. If you feel you found your soulmate though, why would you throw that away? I can see where he’s coming from, but at the same time, isn’t what they had everyone’s ultimate goal? The path to finding him/her is the fun part, I know, but sometimes I just want to get there. What kind of mindset did you have about this when you were younger?
