Input: He broke up with me after 3 years of relationship , saying all that “I’ve got too much to deal with in life that I’m not ready to he in any relationship.” We broke up on good terms and at least we still cared about each other- oh so I thought. 

1 month later, I heard him enthusiastically and loudly talk about his new love interest in gathering of a group of mutual friends. He knew for a fact that I was just 2 feet behind him.  First thing that came to mind was being worried that he might get with girls that treat him like shit (he did before). 

I was at first upset that he chose to lie to me even at the very last moment of the relationship... but later I found out more and more that made me pretty upset and angry. 

He kept saying he did not feel anything for the girl until after we broke up - truth is he’s been talking to some mutual friends about this girl just 2 hrs before the breakup, and it was them who said dude this is not cool you gotta end stuff before you can do anything... so he broke up with me 2 hrs later. 

When we were together, he always told me he couldn’t make plans cos “his mom makes all the decisions” and he has no say over his schedule (he’s 23 now btw.) But to my surprise, he managed to convince his entire family to go on a trip just to travel to see the new girl.

Then slowly I came to realise that he was never faithful. He once lied to my face about how he injured his knee while I was literally kneeling in front of him, doing his wound dressing for him. He lied about the most trivial things, and when I ask questions he would cover it with another lie, then another. 

So after discovering all that, I found the girl on social media. I told her that he lied to me countless times and cheated on me (made out with girls when we were together). I read what I typed many, many times to make sure it was just stating facts, (i.e. he told lies a lot, cheated on me, and the exact time we were together - cos apparently he lied to his family and friends about that too).  I showed some of my friends to make sure the tone was fine. 

All I wanted to do was to let her know... cos if I were in the same position, I would want to at least know that this person (at least “used to”) treat his SO this way, and to take what he says with a grain of salt. 

I was certain there is always a possibility that the girl feels I was talking rubbish, or she might think he’d change for her or whatever. I wasn’t trying to make a choice FOR her. INFORMED DECISION was what I was concerned about. 

Of course, his friends and family thought I was taking revenge. They said “how dare you who gave you the right to do that?” I really, really wanted to say, I really don’t need anyone’s permission to talk to her...? But I didn’t. I apologised for making them feel hurt. 

My ex also kept using the fact that I had been on social media after we broke up - dude I wasn’t the one who claimed to not be ready for any relationship??
