Recently my bil started seeing someone and has taken to spending every waking hour with this person.
Very normal progression of courtship. Look back at your courtship. Did you spend every waking hour with your DH when you first started dating? Was he the absolute center of your world? Were you interested in spending hours and hours of time with your parents and siblings or did you want to spend the majority of your time with your new love

Did that mean that you loved your family less? Probably not - just that you had new priorities in life.

While the whole family thinks it's great he is happy and has a life, he is neglecting my husband and children now and frankly I'm fed up. My husband is very hurt and my children want to know where their uncle went!
The whole family thinks it it great that he is happy - but you think he is neglecting your husband? Not trying to be nasty, but it is not your BIL's responsibility to entertain your husband. He is entitled to his own happiness and his own family. I have to agree with Jules above, and question - is this really about you or about your husband? Are you the one who feels they are losing control? You admit the entire family is happy for your BIL, but your are the one who is upset.

He has always lived at home with my inlaws. My husband has always seen him everyday for at least an hour forever - unless on the rare occasion we stay overnight somewhere - maybe 3x in the last 6 years! We have been together for 14 years and he has always gone to his parents house to hang out with brother - we had 2 children and my husband brings them over 5 days a week while I'm at work so that they can see their grandparents and also their uncle.
Use this as a great opportunity to enhance your lives. You are now free to go out and gather some good friends around you. Make friends - do not be so dependent on one family for your happiness. There is a great and wonderful world out there- go explore. You will find that your relationship with your BIL will become richer and more meaningful for it!

He is/was a permanent fixture in our childrens lives. Now since he has found someone - we don't know details as he isn't giving any and noone will ask - he spends all his time not at home - he hasn't moved out but he comes home from work and leaves right away to go wherever and doesn't return till the next morning to get his work vehicle so it's not like my DH and he are just missing each other.
Perhaps he is not coming home because he is well aware of the stifling atmosphere there? He knows how you will react? I have to agree - give him some space. He has supported your family for 14 years - now it is your time to support him.

Now I'm not expecting him to live his life around ours but why can't he spend even 1 hour a week with his flesh & blood!!! It is like none of them exist anymore.
You may want to really do some deep self-analyzing on why your BIL is staying away from his family. It may hurt, but if you can see the truth, you can fix it and welcome his new SO into your lives.

It's been almost 3 months since this has started and I don't think I can keep my mouth shut much longer.
You may want to rethink this. The only good that can come out of this is that you will create significant hard feelings. Do you really want to take the chance to push your BIL away completely from your husband?

Tonite I have had it...my husbands cat died this morning - we had left the cat at my inlaws when we got married because my husband didn't want to separate 2 cats (his & his brothers) so the cat lived in the same house as my BIL does. Knowing his brother is upset as I'm sure he is too he came home, basically acknowledged everyone in the room with a hi and then left - no more than 3 minutes tops!!!
I am very sorry about your cat. It is very hard to lose a pet. But I am guessing, that just as your husband is seeking solace from you - his wife, that your BIL is seeking comfort from his new SO. Give your husband an extra hug

I'm pissed!!! My husband sounded so distraught when I spoke with him from work - he sounds like he is writing off his only sibling and his best friend.
Perhaps it is time to make new best friends. It sounds like perhaps you and your husband are a bit too dependent on BIL. Maybe you could work on being your husband's best friend!

I would seriously suggest counseling because there seems to be much bigger problems involved here if you are that jealous of your BIL's new happiness.

I'm ready to wait at his house till he comes home and give him a piece of my mind - I'm sick of my husband being hurt and I'm upset that I have to keep making excuses to my kids for him. My son who is 4 keeps asking where's his uncle, when will he be home, did he move away, and he says he misses him
Again, I would rethink this. Your BIL is an adult. He does not need to answer to you. You should be happy for him. And why can't you tell your children the truth? Tell them Uncle is in love -and isn't that wonderful. It is very important that you model the proper love and support for BIL in front of your children.

I really needed to vent and get this out or there may be a fight in the next few days!!!
Vent away. That is what we are here for. Especially if it will keep you from confronting your BIL
But I do have to wonder if this is really a real post. It almost sounds like a convoluted, surreal twist to the movie
Meet The Parents. I wouldn't be surprised to see the OP post that BIL's new SO is not in the
Circle Of Trust 
Perhaps a lie detector test in the garage would put OP at ease?
