Please give me advice I need it bad
My fiancé does drugs every once in awhile crack/cocaine to be specific. Well this weekend he was having a couple of beers with his friends at work and when we went to go home he started to make me miserable by throwing in my face all the bad parts of my life, but then we got home and we were joking and laughing and he received a phone call from my cousin who is a big time crack addict who said he was going to come and get him for a night out... well I was pissed off and I went to go to the bathroom and looked out my bedroom window and saw my fiancé in my car stealing money from me. I confronted him and asked him are you stealing money from me he said yup. Well I needed that money to go to the dr.s and get my car inspected the next day. I got so angry I grabbed my car keys and left and went to my parents for the night. I went back home at 730 am and he was not there he didn't get home till 1pm and has not really said anything to me since I am so angry with him I don't know what to do... its not like he has an uncontrollable drug problem because he can go weeks without doing drugs.. I want to know if I'm stupid for giving this yet another chance, I just wish the occasional drug use would stop... I need advice desperately
