I believe that ultimately the true relations come out and last.
I have lost many friends along the way, especially due to very often moving from place to place / from city to city.
Some people are still in the heart and I know that anytime we can get together again.
If for some reason the relation is broken, then the best thing is to let go. It can only be hurtful to remember and to wonder why. It is not easy to get into people's head. Assumptions can only make it more difficult, you get to loose your time, temper, sanity :) And these we need most, especially during the last few months.
Have a good Palm Sunday my friend.
