Am I selfish

Close friend (always called her my cousin) got pregnant at 17 to a boy who was very nasty. She told her parents she was going camping with her friend but actually went with another boy, had sex with him without protection and said it was fine because she was already pregnant. She rang me crying, wanting to come home at 1am so my partner and I left to pick her up, when we got there she asked if we could drive her mates back in their manual ute or she wasnt going to come back (neither my partner or I had a manual license) but stupid us risked it because she was pregnant and we didn’t want her stranded there after people stole her food and water. I was there for her day and night as she cried herself to sleep, I offered her a place to stay to get away from her home for a couple of nights to clear her head. Whilst so many people were against her keeping the baby, I supported her so she didn’t feel isolated and alone. She asked me a couple of months before the baby was born to be the God Mother and I was sooo excited and honoured she had asked and I said of course. So I spent a little extra on the baby shower gift and the gift when he was born. He went to Special Care Nursery as he was in respiratory distress and stayed there for a week. The night before he went home, I got on Facebook and saw another one of her Family Fiends post a picture of the baby with a onsie on that said “will you be my God Mother?”.. I had seen her an hour before and she not once mentioned it and I bawled my eyes out, it hurt so badly after everything I had done for her. I messaged her the same day she was getting home with her little man and expressed my hurt but also wished her the best and said the other lady would be an amazing God Mother. I did state that I’m not jealous but it would’ve been nice to be told that she had changed her mind before finding out on Facebook and she said I assumed I was the God Mother and I’m so selfish for telling her how I felt the day she got home with the baby! I am so hurt, she has now blocked me on everything. My partner and I have been TTC for nearly a year now with no luck and she knows how badly I want a baby and how excited I was to at least be a God Mother. Am I selfish or do you think what she has done was cruel? :(
