Guys I’m really freaking out and I have no idea what to do.

My boyfriend and I have been together for a year now and he is the sweetest most amazing person ever. I really do love him.

It’s just - it’s getting really serious

Like there’s talks of moving in and wedding and kids

All of this is hypothetical in the future plans of course but is just kind of hitting me how real this is. And idk I guess it scares me

And he was my first and I know it’s awful cuz I have the most amazing guy but I just keep wondering if I’m missing out?

Like how do I know he’s it if he’s the first serious boyfriend I’ve had!? How do I know he’s the best when he’s the only one I’ve had?? Idk like a major FOMO

And I know it sounds awful and I just don’t want to bring it up with him or any of our friends because don’t want to hurt him or make him think that I don’t love him or anything

And I’m really just stuck and don’t know what to do or where to go from here because at the same time he’s planning our future I’m freaking out about being 19 and already having my whole future planned out and being stuck

Can I please get some advice???
