Allways put yourself in the other fellas shoes if you want to understand things.
Your friendship and Love for them were true and sincere, if one of them left the troof whilst you were still being Faithfull to the FDS, how would you have behaved?, possibly you would have treated them the same way they are treating you now, but inside you would still Love them and miss them and wish they would come back so that you could demonstrate your fondness for them.
Probably they are feeling the same way about you.
Its the teachings of the society that are insincere, not your own friends who Love you but belive they have to chose between you and God,
