Divorce and feelings of loss and heartache

Just wondering how im going to feel once sarah and lucas have fully moved out, i know ill get to see him, but its gonna be weird coming home and there is no one to comfort me after a bad night, or playing with sarahs hair to help me fall asleep. Though its my fault that this has come to fruition, and yet i know it will happen, well is going to happen very soon, I just wish i had the power to stop it. Even though i did have the power to stop it and yet i still did nothing about it. i guess all i can hope is that it doesnt happen again, next time, if there is a next time!
