What would you do?

I felt for a long time that I had a good relationship with my mother. I live across the country and we would talk on the phone often. When I went home for holidays, she told me I just like to hear my self talk, only talk about myself, and that she avoids talking to people like me, but doesn’t do that to me because I’m her daughter. She apologized later, but it didn’t take away the fact that she said it and I felt like she meant it. So now I’m home and haven’t talked to her in two weeks. She wants to talk, she has texted me, called me when I was at work and couldn’t answer, but I can’t seem to get up the guts to call her. I really want her to enjoy our conversations, but don’t know what to do! Now when I go to call her, I get anxious. I don’t want to talk too much or say the wrong thing. I have always asked her how she is, how life has been, and sometimes she will call just to vent about something. I thought I was doing a good job of making sure to ask about her, now I don’t know what to change. Yet, if I do change and I’m quick in response and don’t do my normal thing, she will know something is off and ask. I don’t want to bring it up again, but I also want her to be happy and enjoy talking with me. Advice?
