Confused about feelings, help!

I dated this boy for almost 2 years and we broke up 2 weeks ago because he’s joining the military & I’m going to college so our lives are just taking us in two different directions. I was so insanely in love with him. But I know it’s for the best that we broke up because we could never give each other the lives we wanted. Now I’m trying to move on. I met this amazing boy! He literally checks off almost every box on my list. He’s sweet & he really likes me. He’s going to college and has a good career path. He’s very handsome! He’s almost perfect and I know he would be a great boyfriend. I’m just worried that I’m not giving myself enough time to heal from my past relationship. But I’m also worried if I blow the new guy off I’ll lose him. I still love my ex, but I’m not in love with him and I don’t want to be with him because I know we aren’t right for each other. I’m just afraid if I move on too fast I’ll end up in a messy situation. What would you do if you were me? Please give me advice!
