Does anyone else have skids that are SUPER needy towards their non-custodial parent?

I'm trying to not get annoyed and look at it from the kids viewpoint that maybe he misses his dad, but I'm struggling a bit with this since SO won't do anything.

Although stepson(almost 15) lives with his mother and only visits every other weekend as well as 1 night a week during the school year, whenever he wants or needs something, he texts dad, constantly!
