If you've been friends for ages y dont you just ask her out since she likes you ..you will be awesome friends and maybe gf and bf.
How do you know your ex-girlfriend wasnt lying and she really never liked you, thats probably why you got rejected.
Okay, so your ex kinda screweed you over with your other friend here, but all is not lost. Just explain things to her and talk it out. Make yourself look silly and odds are she'll forget it in no time. You could tell her that you heard someone say that she really liked you and that you've been thinking about the situation alot and went over to confirm if what you heard was really true. Then tell her she is like a sister to you and that it's likely for the best that you stay friends. Then go out and get a milkshake or something as friends and laugh the whole thing off. ^_^ (Also, dont let her brother find out... he might get mad) I hope this helps you.
Thats what Im talking about, what if your ex-girlfriend was lying and was trying to play a joke on you. Like maybe she knew if she lied and said that your best friend liked you, that you would ask her out, and then she could laugh when she rejects you.. You get what I mean?
nut if u really like her, sit her down, look DEEP into her eyes, tell u how you feel, then ask if she can give the relationship a chance
