Sounds like you guys both had and have a lot on your respective plates, and your friendship took a back seat for a bit. Unfortunately, this happens in life sometimes. I'd say the best course of action would be staying cordial with her, and trying to rebuild your friendship slowly. If one-on-one conversations and interactions are awkward or forced, try incorporating a third person that's a mutual friend. Eventually, your friendship will rebound. Maybe not all the way, but at least to being good friends.
