Don't feel bad. Everyone does.
The trick is to put on a positive face and hide your pain. You can con anyone that way. The other problem is there is no schooling for learning personality typing and cross personality reactions to each other. You should do personal research on the matter and you will be much more effective in screening potential personality matches to yours in the dating game.
You are not alone.
suck but do you swallow
you ask stupid question like that and tell me to grow up get real
my two final words the second being off
If you dont want to suck just tell him no. If he doesnt understand its not your fault.
I know what your question meant, i was just messing around. i do not know why you suck at relationships, maybe its your partner not you i dont know.
