I don't have my own children, and husband has 16 yr old son. We have him from Thurs-Sun alternate weekends. The child doesn't behave badly, but doesn't have friends or interests or play any sport or belong to any clubs, which I find strange.
Because of this, when he's with us, he just lies on lounge floor, watching cartoons/dvds for up to 18 hours per day. I'm not allowed to challenge this because "he's not doing any harm." So essentially our lounge, which is the heart of our home, is taken over during his visits. I tend to retreat upstairs, but this upsets my husband who thinks I'm not integrating. I try to explain that after a full week at work I don't want to watch hours of The Simpsons at full volume, particularly when the child has his own tv/dvd etc.
Husband is a lovely guy and but he is very over-protective towards his son. For example, he asks his son if its ok, if we want to go out. Or if his son isn't keen on what we're having for dinner, he'll rush out to Asda to buy something different. You can't fault his intentions, but he puts son on a pedestal, runs round like mad trying to indulge him completely, growling at me if I question it. The son doesn't ask for or expect any of this, he generally takes things in his stride.
If this was only an occasional thing, it wouldn't be too bad, but obviosly 50% of our leisure time is taken up, molly-coddling a 16yr old. We don't get much trouble from the ex-wife, but she insists was never vary weekends, we can't ask for a change unless we're literally out the country. I find it difficult,that so much of our lives are restricted by a 16yr old.
Like I said, he's not a bad kid, but my husband treats him like he's 8, and when it's an "access weekend", I feel very resentful. Which in turn makes me feel guilty.
