Death of a much loved father in law

My father in law died very suddenly on Friday afternoon.   It came as a complete shock to everyone.  He was 73 but seemingly very healthy and active.  He was a great man who treated me like his own daughter.  Whenever I saw him, his eyes would light up and he'd give me a big hug and tell me how beautiful I was.   The whole family is devastated.   My husband doesn't know how he'll pull through this.  He always used to call his Dad for advice and guidance on things.  His Mom and Dad had just celebrated their 50th wedding anniversary not too long ago.  They had known each other since they were 14.  They were the kind of couple that was so obviously as much in love 50 years later as they were upon getting married.  I am very worried for my mother in law.   

My husband's mom and dad had both been helping us financially with the surrogacy and have always been there for us to talk to throughout hard times.  I am sad that, if we ever have a child, he will not get to see him/her.  I know my father in law would have loved that more than anything.  I went in his office to try to help sort through papers yesterday and he actually had a file of articles about infertility.  He wanted to understand and help.  I couldn't help but start crying.  He had really wanted to have the whole family together, but never pressured us because he and my MIL understood it would be painful for us to be around Jordan's brother's children.  The sad thing is now we are all here together and we have met some of the children for the first time (and they are so cute) and we have bridged the gap that had grown between his brothers and their wives and us.  Yet, I hate that it took this for it to happen.  I feel like I was selfish and should have done it sooner for the sake of my in laws who were getting older.

I will never again assume there is always time to make a situation right.

My husband is so devastated.  There is so much more to say but the funeral is today and I should go get ready.  It's going to be an extremely difficult day for everyone.
