Ok here's the whiny part. I think you are turning into the father I always wanted you to be and some other woman will get this great husband and father. I know it's not supposed to be about me but I see all these changes he's making and it hurts so much that we are not going to be a family anymore:(
There is no telling what the future holds. labug posts a lot to you, but I don't know if you've read her sitch. If not you should, because there was a long period of time that she was convinced it was over too. Same thing with 25, at one time she gave her marriage a 5% chance! Your sitch is still quite young even though it doesn't seem like it I'm sure. Hang in there, it really is a marathon! It's too early to give up hope!
The signs you saw were positive baby steps, but you turned them into negatives! The fact that he's covering the dental costs when he's rarely if ever offered anything like that in the past is GOOD! Celebrate the baby steps!
