Be true to yourself, to the point you are not hurting your family, as far as outside things, that is where you draw the line.....you are living your life, not one of the 'outsiders..' this is YOU here, YOUR path...
As far as religion, things go on outside of its morals all the time, it's what you are comfortable with, what your particular faith is..
I guess no one ever knows 100% where they are supposed to be,,
Im sorry you are in a dark place........but it sounds like YOU know deep down you would like to make a decision that goes against the grain,,and deep down you know the answer,,,perhaps it would not be acceptable to some....but you are not some...you are YOU, and you have only one life to live
