TITLE: Reddit I have a real life OA(ex)G. What do I do!?
POST: A little over a year ago I walked in on one of my (now ex) girl friend's coworkers balls deep in he on my bed. A few days after the break up she decided to tell me that she had been cheating on me for quite some time. Since then she has been harassing me trying to reunite our relationship. Mind you I am now married to the love of my life and we have a daughter on the way (yeah, I know... it was a little quick). I blocked my ex's number to get he to stop contacting me, hoping that she'd get the message, but this morning I woke up to a text from her.
TL;DR: 
My ex is still trying to get back with me after I left her cheating ass and am now married with a kid on the way. What's the best way to get the point across to her?
