Quoting Onalee's Mummy:" It's not up to you to judge if it was serious or not. It's none of your business she shouldn't drag you ... [snip!] ... drag you in to it however is flip too if my sister dated one of my exes. You don't touch what a friends touched. Ever."
I am not judging if it was serious I know for a fact it wasn't she was dating my brother he told me it wasn't and she is my best friend she tells me everything. She is married so she is obviously moved on being mad at me and making post on fb about me for not sharing her opinion on it is retarded.
