Hi, I think what you are doing is awesome and am glad that the house is refi.

If it helps, my xh went away postdivorce for a couple of years. Like yours, my divorce took forever. It has just been the last year (since my youngest announced his engagement) that he has been batchit crazy again. But his MLC behaviour started immediately after my eldest son got engaged. . . now if I can persuade my middle son to remain single maybe we will have a bit of stability. The marriage of his children is something he clearly cannot handle.

Yours have a while to go on this . . . . !!
