This is perfectly normal. As life goes on you meet more people. It's not practical to keep in contact with even a relatively small number of them. But you don't need to in order to maintain friendships. There are some friendships where you will see or contact others very regularly. But there are others where you will do so less often, or there will be gaps, sometimes months or years, where you don't speak. That becomes more common as you get older, friends move away, you get involved in relationships, get married and have kids, get involved in your career or other interests etc. These things all make it more difficult to remain in regularly contact with friends. Some friendships drift or end as a result, and that's fine. You'll make others, and some will survive that. But you will not have the time to maintain regular contact with everyone, so you shouldn't feel guilty about that. I have friends that for whatever reason I see every two or three years. I have others that I message reasonably regularly, but this is all so variable. And importantly, you cannot compare yourself to others in this regard. Everyone is different and everyone has different lives with different variables and different connections to others. Whilst it's natural to be envious and social media positively encourages it, nothing good ever comes of it, and the one thing you always miss when comparing yourself to others is the negative aspects of their lives that you are likely not aware of, because people usually aren't open about those aspects. Your own wellbeing and happiness is the most important thing. Prioritise the friendships that make you happy. Don't worry about the expectations of others.
