I need to vent but I also need some tips on what kind of questions or statements should be said during couples counseling tomorrow. Here’s a back story:

June 20th, 2018 we got together

November 3rd, 2018 we got engaged

December found out we were pregnant

August she was born. Here’s the “problem part”

4 weeks ago my fiancé went to his friends house said he was going to come home and then didn’t they got drunk, I caught word there was a female supposedly there (mind you my fiancé’s friend Justin and this other guy just ran a train on this female the week before) I was driving to Justin’s house and turned around because I had our newborn daughter in the car and I called Justin’s parole officer because Chris, my fiancé, just his phone off and wouldn’t answer my calls. The next morning I told him to come spend time with our daughter my mother was on her way to our house to help me pack somethings because I wasn’t playing these games. He comes home agrees not to see Justin anymore( they’ve been friends for a while but when then hung out three years ago one of them would relapse on heroin, justin just got out of prison 2 months ago) so he agrees not to see him, agrees to take a drug test, and agrees to couples counseling The following weekend Chris went to the bar with a work friend 3 minutes down the road he then drove my car drunk to another bar 15 minutes down the road then after being there drove to the nearest walmart 40 minutes away for more beer, completely drunk! He promised he’d be home by midnight so we could at least go to bed together he texts at 11:38 and says he’s gonna sleep in the car he’s too drunk. Anyways he ends up coming home I go to check his phone and he wouldn’t let me. There was messages to Justin saying be there in 2. He gets his phone back deletes said messages I get his phone back again run upstairs lock the door and I see messages to a female before I could read content he busts in the door and takes it back then deletes those messages. I messaged the female supposedly he only asked her who was as the bar as she works at said bar. I cannot trust him, he’s an alcoholic, i want to make things work as we have a 6 week old daughter together and my two boys have grown fond of him. He’s a hard ass on my boys but the softest person to his 3 year old using pet names and like I said is just all nice to her but when one thing happens behavior wise regarding my 7 and 3 year old boys he’s quick to jump to punishment. It has grown to make me kind of resent his daughter because our daughter also gets pushed away and her own grandmother on chris’ side wants no part in her life but does his 3 year old daughter. I need advice, tips for counseling tomorrow anything anyone is willing to give. If you made it this far thank you for reading.
