My ex GF and I are still on good terms

My ex GF and I are still on good terms to this day. I felt guilty not opening up being transgender and she wasn't happy at all with me making the excuses. It was 15 years ago, I finally opened up coming out as transgender to her. She took it well and decided to support me. We have two sons together. Said all she wants to see is me live a much happier life. We still talk to each other to this day although she is married. Plus she sees me for her repairs to her BMW. Still calls me Mika and knows the unhappy me is gone that has not come back.
