OP here--
I think the ex has been with the current gf about a year. He went through quite a few gfs after he left us 11 years ago, then got married in 2008, that wife got pregnant and he left her when she was 8 months pregnant. That baby is 1 1/2 now. This is the first gf ex has had with kids of her own. They are not the kind of kids DS gets along with, they are into monster trucks, hunting, etc. Not that those things are bad.
For those who think its terrible how little time non-custodial parents have with their kids, let me assure you this does not have to be the case in our situation. My ex works about 10 minutes from our house and is welcome to come by, take DS out to go fishing, go-carting, a movie or whatever during the week or even on "my" weekends. He does not do that and cancels his regular visitation about every other time. Its been like that since DS was 4.
For whoever asked what I would do if I had a trip planned to the beach and DS did not want to go: Actually, I would not plan a trip without talking to DS first. Our family trips are trips we both enjoy, so I give him several options for where he'd like to go(places that are good for me, of course) This year, he had a choice of going back to Orlando, going to NYC, going to the Grand Canyon or going to Washington DC. As you can see in my ticker, he chose Orlando.
Someone else mentioned making kids go to church. I don't make DS go to church, although he goes almost every Sunday I have him. I was made to go to church and I resented it. I ended up not attending church for 10 years after I left home. I want my son to enjoy church, so we chose a church with a big youth group and contemporary music. So far, so good(he has maybe missed church 10 times when he was with me in the last 6 years)
I'm not worried about being taken to court for one missed weekend in 11 years. He has probably cancelled at least 50 times during that time period.
I have told DS he needs to settle this with dad himself or just deal with it and go. I am going to check where they are staying, because if he is in a hotel room with the unrelated teen daughter, that will not work for me.
