My first girlfriend was one to remember - kind, sweet, lively and fun. But we ended ties three years ago due to our frequent arguments and disagreements with one another, that just drove us insane. I called her some terrible names, yelled at her for the dumbest things, and of course I regret all of it. Just recently I struck up conversation with her, because I wanted to befriend her once more, however she seems absolutely dull now, almost lifeless. I completely understand why, because of me. However, she still chose to talk to me over the phone for a good few hours. We left with a goodnight and everything, but she doesn't seem to want to talk with me at all. Is there any appropriate way I can get her back in my life, as a friend, and perhaps more? Can I get her to laugh with me again?
