I know it's tough, but it sounds like it is for the best. I had a situation with an ex where I found out he had been lying to me about something important. Then when I found out he was lying, he tried to blame it on me, saying I should have known how he really felt. I guess at least that helped me see him for who he really was and made it easier to let go.

You are better without him. It will get better. Sending lots of hugs!
