Yes I've had this happen a couple of times... One time in particular was when a girl told me how she felt about me and all I had to say was do you want to be my gf but I was too shy even though I had a gf b4 her... I felt as though I didn't deserve her and that I would just make her unhappy. Luckily, that was about a year and half ago and since then I have realized that me and her wouldn't have been a good match... I don't know if there is anyone out there that is a good match for me!
