I'll clarify the question. Have you ever done something you really didn't want to do only because you didn't want to hurt their feelings? If so, what was it? Did you regret it?
Yes their are things that I have done with and for past girl friends, that now we are broken up and look back on it I kick my self in the rear and ask myself why I did those thing. I would suppose that it may have been partly due to not wanting to hurt their feelings. However, I did these things more so because I wanted to find out what interested the girl and be able to spend time with her to help build our relationship.
Go out with someone I really didn't like. Who turned out to be gay (don't ask) and If you do please in a message. I regret staying with him for so long and while in the relationship making assumptions, and wasting my time. I felt bad after the break up because I was his only but since I led myself to believe that he was you know he actually when ahead and you know because of me and that's why I wrote a question about him some already know.
