I was not intending to see this, but him &amp; his friends were commenting on a social media post I happened to see, making jokes about me calling his friend a bad influence before we broke up(it was not in a “you can’t see him” way, but in a “you change when you’re around him” way) because they ended up drunk at some girls apartment at 2am months ago, which was out of character for him. and though he literally begged me to stay with him during that argument, he is making jokes about it online acting as if I’m an idiot &amp; he’s a victim. He had a major lying problem, and he knew it too. He dumped me after three years of living together, and hasn’t talked to me since, saying he fell out of love &amp; what not. Why is he still dragging it on with his friends after two months, especially when he did wrong and he proved himself not to be trustworthy with this friend?
