Should I be annoyed or grateful

Destiny

So my child’s father wants nothing to do with his son since he’s in a new relationship and his mom wants to be involved. The last conversation me and him had was he could help out financially but he can’t be physically there due to his new girlfriend not liking us around each other lmao🙄 so I text his mom asking if she can tell him to help out and she ask what things do I need I tell her and she has the nerve to tell me I can get those things from the hospital for free and also she’ll ask his cousins for hand me downs …. WHY do I need hand me downs id rather work my ass off to make sure my baby has everything new then to do that she’s basically saying it’s okay for her son to be a deadbeat and I don’t like that , please tell me someone if I’m being rude or if I have a right to feel that way
