Trust me, say no. who cares if thje tally adds up to yes, say no. I'm telling you right now, don't be with some chick that you don't like. It'll be a pain in the ass. If she likes you that much, its too bad for her. Things didn't turn her way. I mean are you honestly going to go out with her and stay with her cause you feel bad? Then after she gets even more attached you'd feel worse and worse.
My advice, tell her no before its too late. And not to be rude or anything, but dont pussy out at the moment you say no and tell her yes. Just flat out tell her no, and she will get over it. Just dont be like "OMG U R UGLEE I NVR WULD GO OT WIT U LOL U SUK I HT U STOOPID ******". Be polite and say, "well, the answer is no. im sorry, just i dont want a girlfriend right now"
Simple as pie.
That reminds me, im kinda hungry...
