Hi everyone! I am new to this sub :)

I am a little conflicted about what to do. I am 19 and I started dating my first boyfriend a year and a half ago. He is nice to me and overall a good boyfriend except for sometimes when he's stingy about money, but we mostly resolved it. There aren't really any big issues in our relationship and I am happy with him. But as time goes on, I am scared that I am getting more and more attached to him. I want to date more people before I settle down and get married as I am still young. But I guess I have a fear of finding a boyfriend that is worse and I lose my boyfriend now forever.

Am I wrong to think like this? I don't really know if I should break up with him just for the sake of experimenting with other people. I didn't date him with the intention to marry him, but I got more and more used to him and I am scared to lose him. I really don't like the fact that I am becoming dependent on him...

TL;DR I want to experiment dating other guys before settling down but I like my boyfriend right now a lot.
