Ok i didn't understand all of your post but the first line got my attention. Why would you think you can trust them just because they have a common background?? I was a bit like

when i read that.
You shouldn't trust anyone because everyone is fallible but you should trust yourself that you can deal with w/eva.
Did you mean that you can relate to that person better because of your common background?? I can understand that.
I would be carefull of anyone who peed at my party and i deal with people by just comeing out with what i need to say. That's the best way i think because people know where they are then. There are so many two faced people around that at least they know your not that!! lolOl So i would tell them straight how you feel and see how they react. Then i would go to the church that you want, no matter what anyone else says....well apart from your priest you got to listen to him.
