How to be close with my godmother again?

When I was younger my godmom and I were very close. I remember thinking of her as my second mom. Whenever she came up to visit we would play with my dolls and she would tell me stories and I would hug her all the time randomly like little kids do. When I turned 12 all that stopped. I didnt realize how much she really loved me. When she came to visit I became quiet and distant. No more hugs exept for hello and goodbye. They live far now and we dont see them as often, however I was with her for a while recently. I was off and distant the whole time and I regret it. I guess she noticed that and she told me how much she loved me. I feel so bad because I have been treating her like crap. The last day I was with her we started talking again and bonding. I just want to have the relationship like old times? What do I do? Im 17.
