First off, I know this is a minor problem in the grand scheme of things but .... A friend has had a minor illness for a couple of weeks. Messaged her Sunday evening to see how her weekend had been. Friend replied saying it was much better and outlined an activity she had done. We exchanged a couple of messages about the activity and then the messaging petered out. If the situation had been reversed, I would have asked how her weekend 1) out of politeness and 2) because I was interested.
For background, it's not the first time it's happened and also happens in different contexts. For example, a couple of weeks ago we were out for a walk and went past a horse riding centre. I asked if she'd ever been riding, she answered and then the conversation stopped. To me, there was a natural 'what about you?' question for her to ask that never came. I'm trying to work out whether she has poor social skills or has no interest in me, or maybe I just ask too many questions, or am I'm unreasonable waiting for her to ask me questions and should just be jumping in with stories about me that she hasn't asked for.
