Me? or them? sorry its a little long?

No its not really you, you just might not be the perfect girl for them you might be close to the ideal that's why they were in love with you. You are a perfect for some other guy. The question is did you think were the "one"? He may have low self of steam is all but if he truly thought you could better he would have told you straight up. You'll find that perfect someone for it may not just be right now.
