Miss: instead of hoping he will change, hope for change in you. Care about your child and don't worry about him caring. It's a huge waste of energy and will kill your soul.
You want him to love and care about you because that's the only way you can feel love for yourself. It's validation.
You can't get validated from an active addict. You learned this from a Father who's the same way.
You can't make his stop drinking, you have no power there, but what you do have power over is you and your choices.
Keep posting and talking this out
