They weren't friends and you are well rid of them.....
"a friend in need is a friend in deed"
'Amicu certus in re incerta cernitur'. This translates from the Latin as 'a sure friend is known when in difficulty'
That is they are there for you when the chips are down
because people are people !!
because so have some form of motive for doing what that do. may it be peer pressure, or & your not flavour of the month. To many people do favours or so called favours if there is something that they can gain from. True friends are there any ?
Usually if you have stopped being useful to them. Has happened to me many a time and it hurts.
because they are not really good friends
Sometimes people don't fit into your lifestyle and you have to let go of them.
Because their "Real" friends.. :(
there probably is a reason.you just dont see it. best thing you can do is try to communicate with that person.
