i was guilty of this once. reason though....when i was getting to know this brother, we would talk and hang out with groups. Then when it was "official" that we were courting, he changed. i realized he wasn't the person i was getting to know. I gave it a chance but everything about him became annoying. So I ended it quickly thereafter. BUT i didn't just all of a sudden start dating someone after though. Thats the only diff. with me.
