Cocaine withdrawal

Mt bf has been clean for 8 months and having mood swings and getting angry for the smallest things, we are on a long distance relationship after being toghether for 2 years, he left to get clean and start a new life and i am supposed to join him next year, he was never abusive in the past , but since i ve been already in a vervally abuse relationship i dont want to get into another one, i wonder if this anger and mood swings will go away. he received complaints at work about his temper and he was angry many times when talking on the phone. now we have to meet for new years and spend a few days togheter, so how can i help him with his rehab, i tried to get him to see a pdoc or counsellor but he refuses, he says he has other problems more importants than staying clean, i know he is drinking and probably a lot cause his uncle complained about it, saying he has an issue with alcohol, his uncle doesnt know about the cocaine situation, i wonder if he is replacing the coke with the alcohol, how can i identify whether he has really anger issues or is just a step on his recovery? sometimes he gets really down too and is not very open to communication about that. any tips , because i dont want to spend our vacation arguing, specially since we havent seen each other since last easter.

tks for reading.
