try not seeing her for like 48 hours.... cut off all communications.... slp over it....then while you slp, think hard... think really really hard..... when the morning come, take a very cold shower to wake your inner guts out, then tell yourself again that you don't love her anymore --- if you can't, and feel like your missing her badly, talk to her and settle all the differences between you... if you still feel the same way.... tell her how you feel and simply apologize, but be nice to her for at least a month, in that way, at least you can make her feel that you don't really intend to hurt her...
