I need some advice about going back out with my ex?

I think that if there isn't any actual problems between the two of you getting back together, then it should be fine. He went out with you once before, and if he truly likes you, you'll never ''ruin'' his self image, because it won't matter to him what his friends may or may not think of you, only what you think of each other. I wouldn't worry too much about embaressing him or whatever, it's only natural for the girls to be shy ( as I am :P) but if you get any grief from people making fun of the two of you, just put a smile on your face and ignore it, because they don't know anything about what's going on
