I have no patience for an insecure stranger who thinks that I am obligated to explain away her every insecurity. Especially since I have no idea who she is or what is going on in their lives.
Her boyfriend is just my past and haven't you heard? I don't lick my own spit. I clearly didn't make any move on him. Do yourself a favour and clarify everything with the people who are actually involved in this especially your own boyfriend.
I have better deals in hand and I don't need any advice from you.
Your insecurities makes you real ugly.
