help getting over someone

my ex and i dated for only about 5 months, but we had a strong connection. he broke up with me bc the distance was hard to manage, esp with school starting at the time. he started talking to me again months after the breakup, we started hanging out every now and then as "friends". he has since confessed he still has major feelings for me twice, invited me on a roadtrip with him and his friends (which has recently happened), and we even had a drunken hookup not even two months ago. I was tired of all the flirting with no commitment and asked him a couple days ago whether he's planning on being with me in the future or if i can move on. we talked it out, the distance is still an issue and he wants to figure more things out until he dates anybody, so we both agreed it's best for us to move on. this is the first time (even since the breakup) i'm trying to actually move on from him and it's so so hard. i've thought about him every day ever since i met him (which has been a year now). we even started talking about the future together at one point. i can't imagine any other man in my life, and even though i could get one no problem, none of them interest me. i feel so stuck. any advice?
