To cut a very long story short DH is a recovering alcoholic and has been for past 10 yrs. He relapsed yet again last year and I finally admitted to myself that this time really was the end of our marriage. I threw him out and he continued to binge for the next 4 months. (is a high earning professional so luckily had the money to rent a very small flat). However he eventually decided he was going to clean himself up again , begged to come home , blah blah blah .... and I took him back again. This time I really didn't want to but I just wanted him back in the home for my DCs (15 &12). As they love him very much and have a very good relationship with him otherwise.
The thing is however , he's now been back 2 mths and although not drinking he is taking cocaine. I know the signs ( he has taken it recreationally over the yrs) although he is denying it. I also found some so he is most definitely lying.
How do I approach this? I've already made it quite clear that I don't want him to use drugs. He also agreed that he could only come back home on the understanding that he was to be completely alcohol and drug free and that this was our last chance to save our marriage. I'm not in a position to leave , so what can I do? I'm rambling terribly I'm sorry , but any advice would be really appreciated
