Search Results: boyfriend keeps lying

I first met him in 2015, he was lovely until I started dating him. He knew that I was depressed, yet he still wanted to date me; he knew exactly what he was letting himself into. I dumped him within 3 weeks of dating him because he was telling his friends lies about me and people told me everything he's said; he even told his friends I had cheated on him because I dumped him. A few months later we agreed to try again but take it slowly, he started lying about me and my friend. He then completely ignored me for 12/13 months, like somehow it was my fault that he's a compulsive liar. I met up with him this week, I'm a forgiving person; my friends kept telling me to stay away from him because he's no good. I thought ''its been a year since I last seen him, surely he's matured''.
When I met up with him he tried telling me that I cheated on him last year, he then seen my facial expression and immediately changed the conversation; which was very sensible of him because I DID NOT CHEAT.
He then told me that my best friend's boyfriend only tolerates me because I'm his girlfriends friend. I explained to my ex that me and my best friends boyfriend are best friends now, he was still telling me that he doesn't like me. I believed him and messaged my best friend, explaining that I no longer want to come round to their flat because her boyfriend doesn't like me.
After I sent that message I started crying, I looked at my ex boyfriend and I said 'I can't do this' and I walked off from him. The thought of losing my two best friends upset me, when I confronted my best friend about it he told me he likes me and my ex is lying AGAIN. When I previously said he was lying about me and my friend, it's the same friend he lied about.
I then messaged my ex boyfriend explaining that me and my best friend now hate him and I never want him to speak to me again because we are never getting back together.

Do you think I've done the right decision? I literally never want to see him again!
