Happy, He knows that you are distancing yourself from him, thus, the questions, asking for help, etc. When you pull back, he comes closer, i.e., like a moth to a candle.
I know it's difficult having MLCers living at home. They can try your patience 24/7, but if you can sit on your until after Christmas, maybe the stress of the holidays will have calmed down enough for you to think about your decision to ask him to leave. It's better to be absolutely sure that this is what you want and not just because he's annoyed you by not checking in or if you are going to do this to get him to snap out of his funk.
Happy, I will support you in whatever you opt to do...just be sure this is what you want.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
