support #1 ... I feel that you don't want to deal with him anymore ...
so why care about his birthday, like #1 said , the most important thing
is how you guys break up 2 years ago ...
someone cheat ... someone one foot step in 2 boats ? miscommunication ?
argument ? understand too much, and need to separate !
if you don't like him, just remind him, "WE ARE OVER, and Please treat me as a FRIEND ONLY !!! BREAK UP IS BREAK UP !!! IT IS THE PAST AND I DON'T WANT ANYTHING EXTRA FROM YOU !!!"
