Is it normal my life long friend called me a mooch

I have known my friend since 2 grade. A few decades ago. Grew up together. Saw her go through 3 marriages. After each breakup, she came to live with me. Always supported each other. NOW, that we are older, she called me a mooch. I decided to check up on my house in another state. My parents died and left it to me. House is nearly empty. I told her I don't do any cooking there because we dont have garbage service. So we ate out. Then she complained she is cold. I have her my favorite sweater of all time to her. Said she could keep it. Next we go shopping with her sister. I do not like sushi. So I paid for my own sandwhich. Later than evening she called me a mooch. I couldn't believe what I just heard. So many other things I have done in the past for her. Like, when her drivers license was taken away. 5 days a week I would pick her up at home, take her to work and drop her kid at preschool. Mind you I was going 20 miles out of my way. I was late for my work. My boss understood thank goodness. I could go on, but I would bore you sone more.
