Should I be bold, or run away? (Long Story)

Hey girls! I need your advice! There is this guy that I grew up with... his mom and my mom have worked at the same place for over 20 years, and they've become best friends. When we were little, they used to take us and his older sister out and play and everything. Anyway, about two years ago we met again. He started working full time where my mom and his mom worked, and I started working there part time in the summer time. When I tell you that I lost my breath when I saw him for the first time... but unfortunately we didn't talk much. At the time, this other girl liked him and all the other girls were trying to get him and her together. It didn't work. He basically just told her that he didn't have time for a girlfriend. That didn't stop her from liking him, of course. But I kept to myself that I liked him too. Cut to now, him and I have talked and picked with each other just a little bit, not much though. Our moms are still pretty close, and his mom and I have became really close too. She knew I liked him, and she was happy about it. We all hung out, and went hiking and bowling... but that's the thing. We always had our moms with us because they were friends too. But she knew she couldn't force him to be with me, and obviously I didn't want her to. Well, this other guy started liking me and everything, and that guy and I hung out a couple of times. It didn't mean as much to me as it did to him. And when he confessed that he loved me, it scared me. Long story short... I gave that guy a change, but when I realized those feelings just were there for me, I ended things completely. Now I feel like I made a mistake by even going out with that guy, because one, I don't like hurting people. And two, that guy and him are friends. We all worked at the same place... so rumors were bound to spread. Now I don't know what to do. The guy I got involved with told me that he tried to hook me and my crush up when I first got there, but my crush though I had a boyfriend at the time 😒...
