Alcoholism Recovery & Treatment

If a man has a high percentage of blood relatives with alcoholism, does this mean he is more likely to misuse alcohol due to genetic faults or through learned behaviour, or is it a self fulfilling prophecy?

Me and my hubby have been together 4 yrs. and have a 3 yr. old daughter and 2 yr. old son. Everything was good in the beginning,but for the past 2 yrs. he finds every little excuse to leave. If i say one little thing that he doesnt like,he will use it as an excuse to pack his crap and leave! I’m so scared to even talk around him,because i dont know if I will say something to make him leave. He leaves us about every 3 weeks, its like he has a schedule of when to leave! He stays gone a couple days and then calls me crying and begging to come back,saying the same story over again….that he’s sorry and he will change,and like a dumb a** I always take him back,well because I love him and the kids are so attached to him,they cry everytime he leaves.He has left us over 20 times,and I am so exhausted with trying to work things out with him.He has tried counseling but gave up after the 1st visit,I have asked him why he always leaves,he denies a drug/alcohol problem(even though he gets wasted everytime he leaves),and he denies having any affairs as well.He left this last time,and called 2 days later begging and crying saying he will go to counseling if I let him back.I’m scared too….I have heard it too many times before from him.Is it worth it to give him another chance or am I just setting myself up for failure again?

I am considering applying for a Diploma in Counselling course and aiming to become a drugs and alcohol counsellor. There’s a bit of a problem in that I have an old criminal record for Assault and possession of drugs.
I wouldn’t imaghine the drugs one would cause me too much problem as I suppose at least I have some knowledge of the circumstances of the people I would be trying to help.
But will the assault one ruin my chances of getting into this career.
It happened when I was 16 and I am now 28 so it was 12 years ago and my record has been clean since.
Really I am looking for answers from people in the UK as this is obviously where I will end up working.
Am I about to waste £2500 on a pointless course?
