I'm trying to stand in your shoes right now. The problem I'm having is that you don't really now how long this frequent contact is going to go on. Do you know when he's skipping town again? Is he just going to vanish and then you will be left not knowing what it's going to be like when he comes back again?
I wouldn't want me or my kid to be jacked around like that. I would need more to rely on. I would want to have some kind of expectations/some loose form of a schedule that I could trust and plan my life around. But that's ME and my need for some control, not you. You and your sons might be able to wing it better than I.
At some point, you might be too busy for last minute calls and it might annoy you that he just wants to pick you and the kids up and put you down at his whim. For now, you're doing what YOU want to do FOR YOU. As long as it isn't damaging to you and the kids, as long as you'll be able to cope when he's gone again, why not.
