With all due respect...
...please be careful with that whole "man of the house" thing. When my folks separated my mom told me, a four year old, that I was now the man of the house. Looking back, it wasn't fair to me, it was way to much pressure, and it helped create the dynamic that led me to becoming the controlling, passive-aggressive, superman-complex driven man I became (and always looking for a ****ing Lois Lane).
Don't get me wrong, my mother is a great woman and is a great mother. I love her more than I can express and we are very close. However, she wasn't perfect, and this particular thing was a huge mistake on her part. Arguably the only one she ever made with me-- but it was a doozy.
On another note, and more to the topic of this post, I'm glad you understand that it was a really, really, really bad idea to text and ask about the drinking. Back in my resentful passive-aggressive days I did crap like that to my wife all the time, and always got the same result you did.
Well done on recognizing it. Now stop.
Take care, take what you want, and leave the rest.
