Why Does He Have To Be So Helpless?

For many years, I didn't even think about all of the things that I have done for that man, my now ex. Why couldn't he learn how to do things for himself while we were still together? Yes, he was a very hard worker, and along with that, he liked paying his bills on time, keeping himself clean, dressing nicely and eating healthy. He didn't act like he knew how to cook, wash clothing or even write a check, so I did all of those things for him. After we divorced, he got in that kitchen and made his own dinners, kept up with all his dirty clothing and learned how to write checks to pay his bills. He learned how to improve on those things, but he still has not learned how to be a good father. He still remains the same there. He has not learned that by telling the truth it would be easier to deal with problems. He still hasn't learned that by not answering my phone calls that I still know where he lives. Why does he have to be so difficult? Why was he so helpless all those years, not helping me at all ? Maybe an old dog can only learn a few tricks at a time???
