I really don't know what to say about continuing the $ every month. I think that taking care of your spouse is important and it tells a story of commitment and responsibility in the marriage.
In my case my husband and I drew up a separation agreement and were considered separate when it came to the finances....He was ending the marriage(A)
He has now come out of his A fog and has asked for a second chance in the marriage. We still live with the separation agreement when it comes to finances, my choice. Because he has a value system that taking care of your family is the way your suppose to do things the right way, it's important to him.. He would continue to pay for things he didn't have to because to him it was showing love........
I noticed everytime he did that when he didn't have to and I would say he must care or he wouldn't do this......I think your wife might think the same way when she is figuring things out in her head.......
It shows you still care and that is enough for right now.....
And she is still communicating with you, even though it's not loving yet.....
