A home being sold is a serious thing.
My divorce took so long that I asked for a bifurcation. That meant that I wanted my marital status severed separate from any property agreements.
I don't want to scare you, but it took 5 years to get my divorce finalized.
My point is that it's very, very possible for him to be divorced and still have property to settle.
Divorce is not for the faint of heart and being with someone going through it is even worse.
I just want to say that it's highly possible for things to take this long to dispense with. It doesn't have to mean that he's still "in" the marriage.
You came into the picture a year into all of this. As a woman who went through a divorce, I think that would have been too soon for me to engage in a relationship with anyone.
As a now long divorced woman, I would never engage in a relationship with a man so fresh out of a marriage.
No judgement, just my opinion.
There is a lot to divorce that you might not be comfortable with. If you have chosen this man, and you love him, you will have to let him do what he has to do to wrap things up.
