DP and I have been together for a year and have recently been discussing moving in together. He separated from his wife around 18 months ago and at the time, he took out a large mortgage to buy her out of their home and she has bought another house. DP pays the agreed amount of maintenance each month and things seem to be reasonable between them. The agreement was that after the 2 years is up, they will divorce.
I was talking to a friend recently and telling them how DP is moving in and she was concerned that his ex would then change her financial claim as he would then be better off than he would be living alone. Should this be a concern? He hasn't discussed our plans with her yet so I have no idea how she would feel about it. I don't want to push him to get a divorce as I don't want to feel like I'm creating conflict but would it be better if it was finalised before he moves in?
