Hi, CorpusHeart, and welcome to Psych Central! I think it's normal to wonder about the grass on the other side of the fence. But, that said, I do know of people who met "the one" and never dated again, but got married at some point.

You are young, as you said, though, and I am sure there are many eligible guys. I wouldn't worry about the future. Just take it one day at a time. My thinking is that if at some point you see a guy you are extremely interested in, enough to risk losing the relationship you have, then you can re-visit this issue. But I'm not sure about dating just for the sake of dating. You might end up just being used by the guys, in my opinion.

Your boyfriend must really think highly of you. I also suggest you just be glad you have him now.
