It all seems so unfair, where is the justice in all of this?

Well today I was having alot of mixed feelings, one week NC, feeling a bit angry today. I can't seem to wrap my head around how Mr.Narc can seem so unaffected. He is from a rich family, driving a 50,000 dollar car, yet I'm a single mom, looking after 3 kids, struggling. It's like he goes through life with everything given to him, and on top of that can abuse, use, exploit, and toss women without feeling any remorse. Will there ever be justice?
I feel like he gets whatever he wants whenever he wants. Like he actually cried to his dad for a luxury car. what 29 year old man does that, yet I don't even have a car! Some days I really hate him, I hate how he can get everything thru manipulation, yet me being honest still struggles.
Then I start to feel angry at myself for letting him use me for so long, why didn't I leave sooner?
Then, I start thinking about the load of shit he tells me, example, "I got mad at my wife because she was sick and lied about taking her medicine" I started thinking jerk never even bothered when I was sick...guess I'm just obsessing over the wife and wondering if things will be different with her.
I don't know *sigh* hard day today lot of CD going on thought I would let it out on here. He's an asshole. I hate what he did to me and then man could not give one shit. Hope he gets struck by a lightening bolt..sorry I'm just in a narc bashing mood.
