NLW, I think you would be best to get completely free of him, debt or no debt. He is dangerous. He has been showing you his true colors of a long time now, protect yourself. He's deceitful and manipulating, impulsive, irritable and/or aggressive, consistently irresponsible, and unconcerned and not remorseful for hurting or stealing.
Many people may be one or 2 of things situationally, he's the whole package, the real deal.
Stop trying to figure him out and get away from him.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
