Have any of you ever not pursued a relationship with someone because you felt that in the long run they would be better off with someone else? I seem to be doing this a lot more recently.

Since I'm such a private and socially inept person, i often feel that being in a relationship with me would just be hurtful to someone else and ruin the fun that they can have in life. I just don't want to hold anyone back from experiencing new things just because I'm so introverted.
