My kids are 24yo, 22yo and 19yo now and I did not always make popular decisions in their opinion as teenagers. I always explained why I set rules or made decisions but didn't expect them to agree or understand at their young immature age. Now, they frequently tell me they understand now and the are so thankful for the rules I set.
Please don't beat yourself up for being a responsible parent. It's your God given responsiblity. Also, don't expect you AH to be a model parent and back you up when he's not even able to admit his issues. He will not back you up on parenting decisions and that's not your concern. He's not thinking clearly, obviously with alcohol and mary jane in his blood!
" Sometimes being RESPONSIBLE means pissing people off!" ~ Collen Powell
