Genuinely not sure if we are or not.
DH's brother moved away for uni and has lived away ever since, we still live in our home town close to DH's family. We live at total opposite ends of the country. BIL usually visits our home town once a year usually en route to visiting other friends and family.
We get on well with DH's bro and his wife, when we see them we have fun and have lots in common, but they never phone each other, news gets passed to one another by MIL. We are not 'close' but would be there for them in times of trouble. BIL has always given us an open invite to visit, I guess in terms of being polite.
DH's mother keeps on nagging us to go and visit BIL, we have been in the past but it is a very long drive. BIL and SIL work full time and when PIL visit them they stay in a hotel (I can understand this as FIL is a pain). I'm not really sure if they want visitors as they are quite busy. The place where they live, although nice, is not where I want to spend our limited holiday time. I feel that we would have to spend a few days there if we were to get over a long drive and see them over a few evenings. I'd rather have a break somewhere else tbh.
PIL visit them once or twice a year, but I think that is because it is his parents, I'm not sure if brothers fit into the same category.
MIL won't shut up about it, I don't know if we are being unreasonable by not wanting to go and visit that much.
