Why do I feel like this?

Think it is normal. I was with a guy for 8months last year and broke up with him xmas just gone. He was a compulsive liar,really couldnt stop lying for the life of him. anyway, i still get annoyed even now because the more i think about it the more the lies unravel. It makes my skin crawl too thinking about him even now. It annoys me that he treated me like such a !! hope this helps.
