So this is really getting to me and I am not sure if I should say something or not.
My BIL moved to the same city as DH and I about 8 months ago. We got him a job, let him live with us for about 2 months until we hooked him up with a great apartment, let him use one of our vehicles and introduced him to all our friends. Then more recently we set him up on a date with a friend of mine, whom he is still dating and it is getting serious.
Last night I was on a walk with my friend (his girlfriend) and she mentioned that they were going camping with some friends of ours for the weekend. Later that night DH and I were at these friends house and they asked if he (BIL) had told us about camping. Last week they had asked him to let us know so we could come. He never said anything, and we have seen him since. When DH asked him what he was doing this weekend, he just said, oh I am just hanging out with some friends.
Ugh I am so annoyed by him, we opened everything we had to make him feel welcome.
Should I just let it go as his age (22) or say something about him being super rude?

Re: NBR: Vent (BIL)
Younger brothers are weird. It's in the DNA.
He probably is hoping that he'll now be able to create his own history with these people that isn't directly connected to his big brother.
Yeah DH and I were saying the same thing. I just wish it did not bother me so much. I have heard him say that he dose not want to live in DH's shadow. But come on, we don't want him too and if he dosen't want to then get your own friends.
