Please help me~ Should I leave? And if so, how?

I doubt you will be shunned by people for not staying with someone you really don't have feeling's for as the man you want to spend the rest of your life with..shocked, maybe, but they will get over it..don't let other people live your life for you..and you don't need to have someone else in your life first, to get out of this relationship now..you are in a good position, do tell this man how you feel, and move on, with a clear conscience..just by saying that this isn't the kind of relationship you want because it just isn't working for you..you don't have to explain all the things you feel, you can keep that to yourself..
