My first boundary with my (ex)husband was:
" I will not engage with him when he has been drinking"
That eventually morphed into:
"I will not live with an active alcoholic"
He knew what my boundaries were, he kept crossing them...until I decided that wasn't acceptable. He wanted to drink, I didn't want a drunk husband. There was no way we could have a healthy marriage with that fundamental difference between us.
It is understandable you don't want to spend time being close to someone who doesn't seem to respect what you want from a relationship. I imagine your husband isn't healthy enough in his mindset right now to understand that.
If I were in your shoes I would be tempted to answer a text like that with my explanations.... however, I have learned, that I can talk until I'm blue in the face or type until my fingers fall off... but I'm never going to be able to have an active addict understand or CARE about what I am saying, especially not if it contradicts what they want to hear.
It's so exhausting dealing with alcoholics. Hang in there!
