Frankly, If it would have been my girlfriend I would have done the same thing to try and make her understand. But I really think most of other women would understand. Looks like My wife is different.
Ego.. maybe. But I am out of options now. And hiding it from her is not a good option because I hardly get any time alone, we stay together so if I drink there is high probability that she would know.
I think I would try and keep doing it untill she understands and drink without her knowledge whenever possible .
Does your husband still drinks on weekends. What made you understand his needs and desicion?
