Aside from the hypersexuality, I can totally relate to what you said. I became an adept liar and manipulator at a young age due to an abusive mother. I got sick of being hurt and punished over things that weren't my fault and sick of not being shown proper love or affection so I started lying and manipulating my way out of unfair punishments and lying in order to obtain the love that I craved. I became so good at lying and manipulating that coupled with a high IQ, I could deceive psychiatrists and other highly educated professionals in a similar career with ease as early as age 12.

Of course being this way causes me some issues in my adult life. I find that I often lie and manipulate without meaning to. I frequently deceive and push people out of my life without wanting to. I've ruined a lot of friendships and potential relationships over being this way. I'm not a bad person by any means nor do I wish any ill towards anybody; I'm simply too afraid of getting hurt again so I constantly hide behind a mask to protect myself.

I don't know how my story may help you, but I guess I want you to know that you're not alone.

As far as your question regarding avoiding your ex and the other guy, I would say yes and yes. Talking to them will accomplish nothing more than to reopen old wounds. I would also suggest blocking your ex on social media and blocking his phone number so he can't check up on you. While he seems to mean well, it's clear that he's hurt and likely won't ever welcome you back even if you do change, so I would avoid trying to impress him and instead heal your past issues and move on. If he doesn't want you than you aren't obligated to talk to him ever again. While this may seem harsh, even if you do change, it would likely take many months or even a year or more to heal. It is most likely that he would either be in another relationship by then or would be single, yet not want another relationship with you. Don't work to earn him back; work to heal from your own issues. Take care of yourself first.
