None of these are bad things.They're all great. But rejecting socialising with other humans due to a negative experience with some is the opposite of the enlightenment that can be found through meditation. If you only read about things rather than experience them you can't really know them. If you only travel alone you miss out on the joy of travelling and discovering with others. You can do both.
You seem to misunderstand. I don’t reject socializing because of a few negative experiences, I just don’t get any significant positive feelings anymore from the majority of my social interactions, after many attempts, and especially when compared with interactions from long ago. It isn’t just other people, I have changed too. Even interactions that “go well” just don’t provide anything of value. What’s more, I don’t miss it. I much prefer what I have now.
I don’t travel alone, I travel with my partner who is a great companion.
