10 months and still not over him

HELP !! It’s been 10 months and I still think of him constantly. I have to force myself to be extra busy otherwise it’s just him running through my mind all day long. We weren’t even together long and yet i feel this is the worst breakup/heartbreak I’ve ever endured. It was also an amicable breakup. It was only after i found out a few things but those are things that have yet to be proven but a woman’s intuition is strong and never lies. He also moved on pretty fast so that’s what makes it kind of worse because I truly want to be rid of these feelings and thoughts I still have
