i think I don't love him anymore

so, we've been dating for a couple years and we're both in college. I absolute adore his family and we have a lot of good memories together, He was my first. I just don't feel that fire anymore and i'm trying to focus on what I loved the most about him but it's just not working. I been feeling this for a while. He was no ideia, I just don't want to hurt him and regret after, I think I'll wait a little more to assure if I do wanna do this. fuck
