So about a year ago I dated a guy, fell in love with him he was my first love. He and I are Talking talking and planing on getting back together when he’s out of lock up. (Lock up is jail for someone under 18) . But when we first dated he lied to me about drugs and stuff. Even though I try to ignore that it happened it still bothers me. Like we have both changed in a lot of ways and will definitely have a better relationship. But how to I move on from him lieing to me ?
