How should I deal with this problem with my girlfriend?

Personally, i'd dump her sorry ass but you seem nicer than that so I say go with straightforward honesty with a touch of flattering (c'mon, who doesn't like a compliment?) However, compliments are most affective when they're true so go with the facts. Listen attentively but remember to defend your side no matter what. A little crack in your confidence will lead to a huge opening for her to feel an ounce of insecurity...and since she's obviously hopelessly insecure you want to stay clear of that one. If she still doesn't believe you kick her to the curb & find a real woman who knows how to express herself...and not over Faceboo at that. Sorry for being harsh.

Hope this helped. Good luck!
