A.G.
I understand how you feel. My ex did the same thing when we got divorced and I finally had it out with him. I told him that if he didn't plan on picking them up and spending time with them when he said he was .. that I will no longer cover up for him and make up excuses, I will flat out tell the kids, "he's just not coming , I guess he has more important things to do." I also told him that they are going to grow up fast and before you know They will not have time for You because they will have their own friends to hang out with. Time is short and in a childs eyes what you do with them is more important than what you buy them. He finally got on the ball and picked them up on a regular basis. As for the part about him just hanging around the house, Get your son, go to the door and tell him " your son is ready to go, have fun and bring him back by such time" and hold the door open for him. My ex tries to do that too, and we have been divorced for 6 years.
Another thing you can do is if he promised your son to go somewhere and didn't... you take him. Your son will grow up knowing and understanding all you do for him. Trust me I know... my oldest is 18 and recently left for the Navy and she made sure to tell me how much it ment that I kept promises that her dad broke, that I supported her even when I was unsure about certain things I was there. My son is 16 and prefers to hang out at home with my boyfriend and me than anywhere else. And my baby is 13 and well she's a teenager you'll find out soon enough how they can be.
Kids are tougher than they look and VERY smart. He will unfortunately get to a point when he wont get excited if his dad says he's going to do something with him. He will on the other hand always know who he can count on.. YOU. Good Luck and God Beless You.
