You have to come to grips with reality.
You can promise, threaten, cajole, wave your naughty bits or bake him cookies, but there is no future "we" without him doing his part.
You're being ready, willing and able just isn't enough, if he can't get his shit together. He's got to want it....he's got to do it.
Remember the third part ......the part about being smart enough to tell the difference between the things you can and cannot do anything about.
Knitting, goldfish training or learning the Bagpipes, will keep you occupied in the meantime.... it'll also teach you patience.
