For the first month after meeting my GF all she would say is, she is too nice. That was her biggest complaint for a while. I am working on listening to any complaints and validating. One of her biggest now is, I love my GF more than her. I try and show her so much love, I don’t know what to do. That’s why I go to therapy with her once a week. I am trying so hard!!
First of all let me commend you for taking your D to therapy, you are an awesome dad! No question of that. Second, if your GF being "too nice" is the biggest complain she can come up with, then this sounds like a case of teen rebellion. My younger D was about the same age as yours at BD. Even though my XW was the one that had an affair and left, I became the lightning rod for my D's raging storms over the whole situation. She treated me very badly for a good year after BD. But I held my head high and continued to try and be the best parent I could be to her and her siblings. A couple of years later we were on vacation in Arkansas and she and I went for a hike, and she brought up the D, and said (paraphrasing, it's been a while) "you know dad, most people don't stay married forever. You did everything you could to save it, but you and mom had twenty great years together and raised us and we turned out pretty good, so I'd say that was a really good run." I was really proud of her for saying such a wise thing! And it really warmed my heart, and at that point I knew we had survived it and were all going to be OK. So hang in there, continue being a great dad, she is probably still grieving the loss of the marriage and hasn't reached the acceptance phase yet. When she does things will be much smoother with her I am sure.
