What can you say as an icebreaker to a mom who is jealous of you?   

I love my mom dearly, but I feel she is very jealous of me. She wasnt supportive of me in high school sports, she always complains when I need to borrow $ (WHICH ISNT THAT OFTEN AND I ALWAYS PAY HER BACK), she has renigged on agreements her and I have made numerous times and she is always 'unavailable' when I tell her I need a big or huge favor. I cater to her every need and I feel every year we are growing further apart... what can I do?
I dont want to have to cut her off, but that is what my heart and my best of friends tell me to do. I dont want her to hurt me anymore...

1st of all, I am 25 and have been out of the house since 18. I have always had a job and asked her only for $ when times got real tough. This is not movie or clothes $ i am asking for here. I payed my way through college with minimal help from her because I had scholarships and I worked 3 jobs! I know for a fact she is jealous of me because I have had other family members tell me so. I am not a needy daughter like some of you have hinted at and to be honest she calls me for more favors and I never turn her down. She takes advantage of the fact that I am so giving and I hate it but cant say no cause she is my mom. NO WE DO NOT LIVE 2GETHER. We were supposed to when she wanted to leave her loser bf, but she backed out on me so I told her never to ask me again to move in with her... Now you can answer the question correctly since you have more details...
