What a sad, sorry, selfish excuse for a man.
I've had my moments with DH don't you worry. There are days I'd rather be single & days I honestly wonder why I'm not.
But he's working on it at least. & even though he's not very understanding or helpful, he's never left me. I have wished he would, but he hasn't.
You guys don't need that crap. Your DS doesn't need such a lame father. At least if he's not really around - living away - you don't have to worry about making excuses for him all the time.
A good friend of mine has an xp who maybe see's their DD every 2 - 3 months. Its supposed to be every 2 weeks. Their DD is 7 & I'm so over seeing her heart break every week or two.
