My boyfriend proposed to me, but I'm only 19.

I (19f) have been dating Lucus (19m) since 9th grade. Throughout the years, our relationship has been perfect. I love everything about him, including his family. We don't go to the same college, but it'd only take about 40 minutes to get between the two, so we see each other most weekends.

Last night, we were walking through a park in the city I go to university in, when he proposed. At first, I was silent. Finally, I asked him to give me a little bit to consider, and walked home. I think he's hurt by all of this, but I just don't know what to do.

I have no idea what to do next. Yes, I love Lucus. Yes, I want to be with him forever. But I'm just so young. I don't think I'd care as much if it weren't for the fact that my mother made a mistake in her first marriage. When my mother was only a few moths older than I am, she got married to a guy she'd met before college. The guy turned out to be very toxic and manipulative, and they divorced a year later. Even after they seperated, my mom was still contstantly harrased and even got fired from her part time job because of him. This has got me paranoid that I'll end up marrying too young and mess up my future.

I feel awful. Lucus is the only one I've ever loved and I can't imagine a world that he's not in. I just needed to vent a little.

Edit:

We met up and I accepted his proposal, with the agreement that we would wait til we are both out of school before getting married. That's all I really have for an update. Thank you all for your advice. Bye
