It feels so wrong, but it also feels right...

So, I've been texting my ex/daughters father -- because he's a true piece of shit. The only time he calls to talk to our 5 year old is on her birthday. No gifts sent or anything, just happy birthday. Last time I talked to him, he lost his trucking job because he kept getting stuck in ditches doing illegal u-turns. He refuses to get a job because he knows that child support will request more money, the same child support he forced his mom to pay so he doesn't go to jail.

Here I am taking care of a child on my own since 18, with decent help from my family thank goodness, but he can't be bothered with a phone call to see how she is? Can't get a job to help support her? I hate that I chose him and all but he wasn't like this at all. I hate him with every bone in my body.

So, I've been texting him mean things from a texting app. Saying how he's a dumb ass and a pathetic excuse for a man. It feels so good to be able to say everything I've wanted to say to him for so long but it feels wrong because in the back of my head I feel I'm hurting his feeling or self esteem. I truly don't care because he's getting what he did to me the first two years. But then again I believe in karma so.....

Should I feel bad?
