“Because you are a kid” is not a reason for a 12 year old. Sorry.
If a kid does not want to spend time with a parent, there is usually a very good reason. And from what I’ve gathered, not being home much and medicating anxiety with alcohol could be a reason.
I think the reasons why your kids feel this way really need to be explored rather than to say “ because you are a kid” especially at 12 and 15 years old
