Relationship help

So long story short last year I was in a relationship (about 7 months) ((currently I'm a senior he's a junior but he's literally barely a month younger than me and age doesn't bother me)) some stuff happened and we broke up. We went through a lot of ups and downs after the breakup. But over the past couple months have gotten back to being really good friends and he's one of my best friends, like life without him sucked. The other night we were hanging out and kinda got into some deep chats and we both admitted to still having really deep feelings for one another. We are "seeing what happens" Am I crazy? I missed him so much and hated life without him. Opinons?
