How do I deal with my mom's creepy drunk boyfriend?

[Sophia15f]

My mom's also a drunk and we live with him, so I don't know how to approach the whole situation when he's supporting us.

This sounds like a red flag situation. U can avoid them and or move out.
Such people are never good company.

And by your pic I can guess where this is heading

Avoid him would be for the best

avoid him as much as you can?

Talk and set clear boundaries.
