My children's dad has them every other saturday night. No phonecalls, no trips, nothing inbetween despite the fact that he only lives 20 minutes away.
During the summer holidays he has not asked to have the kids anymore than this, despite the fact that his usual excuse for NOT having them Sunday nights for example is that he is apparantly incapable of getting them to school 
they're 11 and 13 so this is bullshit.
Lately he's decided to ignore all my texts. I say "all my texts" but the only texts I've sent him are to do with the kids. School report, picking them up at a certain time and one about Christmas. All completely ignored.
Yesterday I sent him a text saying "any chance you can have the boys a bit more during the holidays? Some Sunday nights for example as they're not at school" - as predicted - no reply.
What would you do because I'm starting to get very narked about this whole thing. Do I send a stronger worded text/facebook message (if so, can you help me word it!) or be the bigger person and leave it?
