How long does it take to get over a lying partner?

Hey gaybros, to any of you that dated a guy who deeply betrayed your trust, whether it be cheating, lying, or anything else, how long did it take to get over?

My ex was a pathological liar and did a good job at hiding it for a year. When I found out, it shattered my reality. I don't think I'm over it or anywhere close and it's been months :(
