As a former Meth user I can tell ya that it takes a person very far away from the real world.You seem to still remember how it was before you kicked him out.
He is returning from another galaxy it is a long trip....
You are doing all the work at home not having sex....
I need to breathe, eat, sleep, exercise, work, and take care of me. Sex is not a need in my opinion cause it does not kill me to do without it. I may want to have sex but I have realized the vast difference between needing and wanting.
I can get more out of jumping rope than obsessing about sex if I don't obsess about jumping rope.
To your H meth probably felt like a need but do you think he needed it? Well he needed it to get to that crazy place that allowed him to steal and lie.
I used to want meth so I could stay up for days and have lots of sex. I thought I needed it until I realized the difference between needing and wanting and the feeling of obsession that disguises itself as a need.
Another thing I can just about guarantee you that if your H sees you enjoying your life he will want to be a part of that...
