I'm not going to ask bridesmaids for more money
What is making you not want to ask them for more money?
I'm going to raise a child. I'm going to be sure he/she is considered as mine, even if he/she will not be born actually from me
Your child is the one you raise, has nothing to do with biology. Bridesmaids aren't obligated to give you any money and you don't have to ask them.
That's good, I thought that was ok.
It sounds like you're going to take my advice and that is great, I am happy that you're not going to ask for any more money and raise your child!
