Can this relationship be fixed and how if it can.?

Felling love with single mom and great daughter. She is struggling, so I have helped her allot. I am a mechanic, and her car broke so I fixed it. Needed hard to find parts, so it took a few days. I got it fixed and she called and blessed me out, and screamed at me. It upset me so bad that when she said she was coming to get it, I screamed fine it it off my property. It has been 3 weeks and she hasn't talked to be but one time. I apologized and explained, I shouldn't have yelled but she want budge. I went to see her and she called her uncle to run me off. There is no salvaging this is there, if so how? Any ideas?
