Relationship Advice

I've been with this boy for almost a year (11ish months) and he is super sweet. We love spending time together as a group or just the two of us. He is kinda old fashioned and like to pay for everything but I can usually convince him to let me pay sometimes. I love him but I've been confused recently. This is the boy I lost my virginity to and I thought he could be the one. Now we are both going into our second year of college with at least 4 to go for each of us since we are going to graduate school after. I've begun to notice other boys more and think about how fun they would be to hook up with or even date. I'm on the cross country and track teams at my school and we've been bonding with the new freshmen and one of them is super great. We are from the same township but went to different high school, so didn't know each other super well, but we've become pretty good friends the past 3 days. My past 2 relationships have both ended just before the one year mark for different reasons, but is it worth risking what I already have. I think I just have major fomo.

Well if you made it this far thanks for bearing with me and let me know what you think I should do. Feel free to ask questions
