Is my friend jealous of me?Ok...I met my friend in college...?

When I was in College I met my friend, well in the beginning I didnt like her because she like to talk bad about people, she was really selfish and sometimes she was really mean to other people. Well my brother always tell me why do you talk to her?she is so mean. Then I decided to stop talking to her, noone in school wanted to talk to her because she is really weird. Well one day I was walking and she came to me, saying that the best friends you make in college... I was like I cant be like that...so I keep talk ing to her....Well she is always having problems.. she is always having problems with her mom, and I am always there to listen to her..always no matter what...even if I am busy I am always there.... instead when ever I feel sad she never answers the phone instead she ignores me...oh yeah but when she calls me I am always there...Well today I had a fight with her... She is always saying that she wants to leave her house because her mom and everything...I am like well you are 21 years old you are old enough to move I guess....but now she wants to open a gym she wants her mom to be in the business well I dont care if she is the business or not it is just I am tired that she is always talking abd about other people, ok when she told me that..I was like are you sure you want to open a gym with your mom you are always complaining because your mom destroy your relationship with your bf. Then she is like what don you like my mom? I am like what? you are always talking bad about your own mom. everyday....I always get quiet but you are always what you think. So I was like I got go.... I delete her from my friend list... and I am like what people are like that? why/? I just got marry and she was my only friend....I had friends but any of my friends wanted to hang out with her because the way she is..so I was always defending her...but now i realized that they were right...but now I dont have any friend...it sucks... I just wanted to let out because it really hurts me...I trust her and everything. I think its not fair.
