Hey guys I need some opinions on whether this is the right thing to do or not...
I recently went through a miscarriage - I wasn't with the father but we had been friends for 2 years and for 8 months of the in a casual relationship - anyway from the moment he found out I was pregnant he was dismissive and wanted nothing to do with me or the baby which I sadly went on to loose. When I told him I had miscarried he didn't even so much as acknowledge the message which I thought was wrong that he didn't even say "hope your okay" or something to that effect because as I said we had been friends for 2 years. After about a week I went out drinking to try and have a good time and get over loosing my baby. Rightly or wrongly and because I was emotional and alcohol fuelled I text him telling him I couldn't believe that he'd turned out to be the way he was and I was so upset that he had just abandoned me. He responds saying that it's hard to play games with people who don't give a fuck 

which I feel isn't a normal reaction to knowing that someone had just gone through a miscarriage and just wanted one word of support or sympathy from someone who had believed for so long that they were a true friend.
Anyway I am friends with one of his friends who know that I was pregnant and went through a miscarriage and that the father was a complete and utter scumbag to me but now I am considering telling them that he was the father so that they know exactly what he is really like and completely embarrass him over his disgusting behaviour which he has hidden from everyone else cause i don't think he has told anyone what has happened.
So opinions please on whether this is a good idea or whether it will end up backfiring on me. All I want is for him to realise that his behaviour was disgusting and that he is wrong in what how he has treated me.
