I had a very good friend in my last workplace. She shared an office with me and we really enjoyed each other's company. About a year ago I left that workplace and we remained good friends, until a few months later we had a big fight (our first fight ever). Our friendship never got back to what it was after that fight, althgout I'm sure that we both still like eachother a lot. We meet every few weeks, we send e-mails frequently and we talk on the phone every now and then, and it's always fun -- but on the other hand, she hardly ever calls me, sometimes she doesn't answer when I call her, and I don't really know what's going on with her. I don't think she gave up on me and I'm sure she still likes me.
Do you think it's just beacuase she's like that, and I simply couldn't see it when we worked together? I would really like to get closer to her again, can someone give me an advice how to do it?
