This may be stupid, but I have been married for 11 years and I have no clue where to start and have almost forgotten how to flirt! A friend and I went to a concert a few weeks ago and a guy said Hi! I said hi and kept on walking! She was like you DO know he was flirting! No I did NOT know! Lol. I am so used to being the 'fat girl' for years now that I have forgotten what it was like before I started gaining weight! Any advice!?
