Our oldest son has been with his girlfriend about 4 years now, they are early 20's. GF's family seem to be getting more religious, Dad reads bible every evening, they believe Ethiopia is some kind of promised land, they're very secretive about it, and very insular, our son asked us a while ago not to tell anyone else about it, DS has been living with them for a few months, we feel hurt because he never wants to spend time with us, he'll shoot by, stop for about 10 minutes and goes, like he does the bare minimum. Girlfriend has never eaten with us, and never socialises with us, like ever. He has now told us he and they are not celebrating Christmas and not to get them anything and he's spending Christmas day with them, we do feel very hurt. He says it's not Rastafari, both parents have Jamaican backgrounds, any clues?
