Dating an alcoholic.

Its so hard. I cant trust him when hes out. Im always worried he will drink and drive. As he has had two previous duis. Im so emotional. I guess I just need support as i cant talk to my family about it. We were supposed to go to a concert last night but i got the stomach flu so i couldnt leave my bed so he ended up going hanging out with friends an hour away from home and was up all night drinking couldnt even get ahold of him until just now at 1:30 pm since his phone had been off. I got upset about it. Idk if im in thr wrong or not. But i feel he shouldnt be out drinking with his friends anymore especially since hes going to jail in a couple of weeks for failing his ua in treatment for drinking and driving. :-(
