So many of our SKs remind me of him. They blow their money. Others act out. Many are rude. Many do lots of stupid things.

The Prodigal Son got welcomed back with open arms by his father. I think many (not all) fathers on this site would do the same as they love their kids unconditionally. No matter how badly they screwed up. I think many of us (not all) would welcome our kids back the same way that father did, no matter how badly they screwed up.

So where does that, in your opinion, leave us SPs?

For me, it meant supporting my DH in his rebuilding his relationships with his kids. It meant treating my SDs with basic civility and respect. It meant making myself absent when DH and each SD wanted to do stuff together. It doesn't mean I got over my bad feelings for them overnight (most of which weren't their fault). It doesn't mean I became their buddy. It means I treated them with respect, stayed out of their issues/relationships with their Dad, and I slowly built a new relationship with each SD. I still do all of this. It works for us.
