You get a meeting together with your daughter and son and explain to them the weekend didn't meet your satisfaction so he's giong to be asked to leave... A layabout husband frolicking on facebook and playing video games isn't a good example for him to be setting in the home, not to mention his attitude towards you.
He had a chance to change it so now he's out.
Start packing his things and he will probably complain.
Tell him he either participates in the marriage and family or he knows where the door is.
No one to expose to?
Expose him to your friends or invent one. A trick i suggested earlier is to wait til he's coming home and be on the phone in earshot of him... Talk about his behaviour right out in the open on the phone and explain his plans for abandonment and his dishonestly etc... paint him out as a bad husband and father... Aim for the groin here... There doesn't even need to be anyone on the other end.. He can still experience public humiliation watching you expose him over the telephone...
He will want to know who you were talking to... Just tell him "a friend of the marriage you don't want to be part of, so he can mind his own business"
