Hi, looking for some advice. My friend and I had a conversation as they feel we have been drifting apart and that I don’t seem interested in having them as a friend anymore. We meet up at least every couple of weeks, but they mentioned I hadn’t asked about their immediate family member who has been unwell for a period of time. I thought they would want to have the friendship as an escape from everything going on. They mentioned that if I didn’t reply for a couple of hours or even a day, then they would do the same back, and seems petty to me. This is something that I haven’t experienced with any of my other friends. Does this sound immature or am I a bad friend?
