I'm confused why you can't invite say 4-5 friends and that guy… if he doesn't show there would be other ppl there anyway… you seem to be wanting alone time with him
I don't get how girls get mistreated by some guy, yet they always come back to him, get hurt again and then say "guys are blablabla" They go on this rampage about how guys suck! When it's their fault for going back to the same person who has hurt them before. Always making same mistake over and over again?
Assuming why he stood you up is never good, any guess is liable to be the wrong one. Ask him, if you truly want him as your friend then be upright with him. Clearly the 'stand up' situation bothers you. As the new situation involves a religious event doing something petty as standing him up is stressing 'an eye for an eye' too far. Clear the air regarding the first situation before attempting to make a possible second one.
