with all the people on this earth and as young as you are you can find another guy who is sweet and nice and who will love you on the terms love is supposed to be on (not cheating or drinking or using drugs).
You XABF sounds like mine. He was a huge pot user but I did not know until he moved out. He smoked a LOT and it was a pipe and I thought the
tobacco" smelled sort of funny.. Well, it did cuz it was Weed he was growing in MY BASEMENT.
Mine also "used to use" Cocaine freebasing it. I think he was back into it this past year.. he got $$ from his Mother's Estate and he started lying up a storm and I found out he had a side girl he was sleeping with.
Dolly is right.. move forward and you will be so much better off. You cannot love them better. God knows I tried to.
