Alcoholism Recovery & Treatment

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?

x hasnt wanted any contact with my 3 kids in 7 years, he was hooked on methamphetamine,spent time in mental facility for paranoia, as well as jail time for putting a shotgun in my mouth in front of my kids 9 years ago, called 4 first time in 7 years threatening to kill me if i dont let him see the kids…we did have a visitation 9 years ago, but he never saw them, I asked him to get drug & alcohol counseling also anger managment first..what do I do?
