Husband lies..selling drugs?!

I went through my husband's phone.. I found 2 girls (one he dated while we were separated) asking him for hydrocodones and how much and when he could get them from "his guy".. I confronted him about it and he just got angry that I even looked through his phone and he BLOCKED me for a few hours until he calmed down. That night his phone was blowing up.. I asked him who it was and he said "oh a dealer I knew before I even met you got out of jail.. I didn't know who it was at first and I don't know why he's still calling me" fast forward to the day after this and I went through his phone again..I found out that wasn't true (of course) and he was asking for what these women requested.. he was asking prices for Yellow and white "dros"...

How do I confront him about this? I want to make my marriage work but he is lying to me all the time and gets mad when I look through his phone and find things!
