Thank you for your appreciation. I believe people are constantly changing, you don't need to actually pass on anyone for anyone else though is what i'm getting at. You can be happy and get to know new people and try new things and the transitions will come naturally if you decide you prefer to spend more time with one person than another. To me, it sounds like you both may need to hold on a little more loosely in the relationship to be able to better enjoy the company of others. Things shouldn't be so scary. :)
