Rant for the day (non pregnancy related)

I got my income tax last week. A pretty good chunk. I did not tell my mom because I knew she would ask and I wouldn't be able to tell her no. Well of course she found out. Hiding that kind of money isn't easy. Within a matter of 4 days I gave her well over $500 PLUS bought her anything she asked for. Well this morning she came to me and asked if she could "borrow" some money until she got her check. I told her no and ever since then she's been so mad at me....just why? Last time I checked, I was the daughter and she was the mother. Now I don't mind helping. I actually enjoy giving. It makes me feel good BUT there is a huge difference in giving and being taken for granted. How in the hell is she going to be mad at me!? I don't owe her shit! I have a family I'm trying to support. She then had the nerve to look at me crooked and make a smart ass laugh and say "I know you're not broke jaycee" Well no mom I'm not broke but my money is my money! I think I've done enough for you! AND on top of that, my son's father is super pissed at me because I didn't give him half of my tax return. Now this man is am incredible father to our son BUT I don't owe him shit either. He gets Axel on the weekends and DOES NOT pay child support! So tell me once again...why would I give him anything!?? I have our son 98% of the year!!!!
