I'm new here but I need help with my conflicting thoughts

For years we have been struggling with my husband having issues with drugs. Only it wasn't until last year that we discovered he had an actual addiction to opiates. For years I think I have been naive and blind to things that were always there however I pushed it aside
Few red flags
Prior to us getting serious I knew Of him having 2-3 DUIs but I was young at the time and thought it's in his past and I didn't drink heavenly or do drugs so he called me his angel

We married 2011
July 2012 he had wreck in middle of the night and I found out by having a cop call me and wake me up to tell me he was in a wreck and on way to hospital. I didn't even know he had left the house. He was under influence of alcohol and drugs ( not sure what ).
My dad was in hospital this exact time for cancer so I think I was overwhelmed and not able to decifer what exactly was happening because dad too precedent. My dad passed that December
The following year I had given birth to our daughter in may of 2013
I gave him responsibility for the bills since I didn't want to have to keep up with it on my own and taking care of new born. Money got wierd for while. And I stressed all the time over us having so litttle. He always maintained he would take care of it. Mind you I'm very independent have always had job and made more then him so I sometimes resented him for spending. He didn't always get up for the day and would some times stay up all night or leave unexpectedly in the night. We had random people in and out of house and he would sneak away. This happened for some times but he always had and excuse
Fast forward to summer of 2014 and I had to confront him due to massive withdraws and overdrafts. He and his parents and I had a sit down and after much pleading he yelled out he had been gambling. This didn't hold up with me due to he doesn't even follow sports. But he maintained this was the issue and even went as far to say he owes a major debt and that we could be in danger if we knew anymore. His dad "the enable" agreed to give him money to pay off whoever the person was but my husband didn't allow his dad or anyone to go with him.
Fast forward a year 2015 and same thing. Mommney is going and in large increments. He withdrew what was not there causing overdrafts only his dads account was linked to the account and it automatically credited the money back. We again confronted him this time drugs were definitely the issue due to he was disappearing at night not coming home. Never sleeping and we found him high in cocaine saying he had to use one more time. He went to detox soon after attempting to withdraw from pain pills own his own ( he admitted to taking 10-12 a day and would use money on those and cocaine. Said he became addicted after wreck in 2012 )
He never admitted he was addict just that he got use to taking them. He agreed to go to outpatient rehab and competed a program however he wasn't ever fully Honest and after the completion of it he never went to anything again.
Fast forward to present day. I have sense got my own account and have tried to be supportive. But in recent months I have started to be suspicious he has had some of same friends come around that I have told him i do not want around due to past history or drugs , one of his friends is in rehab , he again is making large overdraft charges and withdraws , never sleeps. Never comes to bed, ,couldn't tell you last time we actually had meal together. He has been known to stay in garage all night and found in morning asleep in there in a chair. He refused to take a drug test recently and said that I just have trust issues. Says the money was for the business he owns with his dad and that is dad agreed to it only that when I told his dad few weeks ago he withdrew again from the account that is linked to his he denied knowing about it and was enraged when I told him that his son had opened up 1-2 credit cards which he claimed were for the business but that his dad denies knowing about or approving. My husband also in recent weeks had mysterious calls one night to a female who he has saved in his phone along with calls out to the friends I don't like in between. He said he was Asked by A Narc to help bust them and that is the reason for the calls. He also stated someone has been saying he is doing heroin.
That sums it up in the best rambling on kind of way I know it's a lot but I wanted to include everything i could recall and that isn't even all of it.
So am I crazy??
Is he using again?
He has maintained I'm paranoid and he is not

I'm self doubting my suspicions again but I feel like only because I'm going to go through with divorce this time. I can't keep my daughter in this lifestyle anymore. I hate it I do and I wanted a family so bad but nothing is worth her health and well being.
