Abusive adult child and enabling wife
I have an adult son who has recently returned from college. Aside from a couple of online courses over this summer, he has met the graduation requirements and is done with his BA. Over the years he has acted in an abusive fashion towards me (outbursts, unreasonable demands, tantrums, etc.) and my wife of 31 years has acted as more of a mediator than someone standing with me to explain the rules to my son (act appropriately or find another place to live).
At times, he has made my life impossible and I've left for a hotel for a day or two to get out of the line of fire. My wife has acted as his enabler and has not pushed him to look for work. He sits in front of the TV all day and plays video games while I am off at work.
I have repeatedly told him he needs to act appropriately or must find another place to live. My wife refuses to back me up and typically takes his side. Since the house is jointly owned, can I somehow evict him even if my wife refuses to cooperate?
Another option is to leave the abusive son and enabling wife and pursue a divorce. This is an increasingly attractive option since I don't have a marriage to speak of in any case.
Any ideas?
