my husband used the same excuses and so did i when i was using. thats all it is to me too, excuses. i think that its up to you to stand strong in the set boundaries and follow through, you can't stop him but you can stop how his using is effecting you, your choice.
yes his feelings may be valid to him but there is still not enough to use over. drugs only magnify the problem to all involved. sorry that you are going through all of this, but it is his choice. you have to do what it takes for you to live the life you want with or without him. keeping you and him in my prayers.
its called addictive stinking thinking i believe.
