@bnthome I can understand your concern.  I was excommunicated about 8 months ago.  You're right, things will work out in eternity. 
My wife really struggled the first few months with not being sealed.  We have 'missed' some things.  I was not able to baptize my son when he turned 8 this year.  I couldn't give my kids back to school blessings.  We had to call a local bishop for a blessing when my wife got sick on vacation.  But each of these, have given other people opportunities to serve.  My kids have been able to see extended family and ward members exercise the priesthood power.  When I told them about being ex'ed, and explained that eventually I'll get baptized again, she excitedly asked if she could be a witness.  (I'm choking up now just remembering how touching that was).  
The Lord will take care of you, your kid(s), and your husband.  In this life, not just the eternities.

I guess I’m talking about the blessings he could be missing out on if his father doesn’t choose the covenant path. I understand things will be worked out in the eternities. 
 
“Those who shall hereafter rule and reign in eternity as exalted beings will form a patriarchal chain which will begin with Father Adam and spread out until every exalted person is linked in. Exaltation consists in the continuation of the family unit in eternity, and every family which so continues will find its proper place in the eternal organizational framework which the Almighty has ordained. None will be forgotten. Unworthy mortal links will be dropped in eternity, for there is no family in which all generations will attain exaltation; later generations of worthy families will be welded into the links formed by their ancestors who became worthy of a like exaltation with them.” (Bruce R. McConkie, Mormon Doctrine, p.558)

Hi @bnthome, I'm an LDS Christian lady married a great generic Christian dude.  We have a little daughter.  
Ultimately, all covenants are about a person embracing Christ & His ways: they want to be that upright person, walk in His ways, have the goodness that comes from it.  It is first and foremost a matter of heart, with actions following that.  My husband is a great person and husband, but he's not yet formally taken on Christ's name and stepped up to that plate.  
Therefore, today we are not yet sealed.  Because we as a couple are not yet sealed, today our little girl is also not yet sealed to us (parents bond has to come first).  
What tomorrow holds is not yet know to us mortals.  But I do have faith that my husband will eventually come to fully embrace Christ, formally take on His name, and formally make covenants with Him.  It just hasn't happened yet today.  And that "tomorrow" is probably not a literal 24 hours from now.  It may not even be during this mortal life.  But I do have faith that it will happen, because I have faith in God and the good man I know my husband is.  
 
Likewise is the case with every other person on this Earth: they'll all have the opportunity to come to Christ and be formally one with Him/each other.  Whether that comes in this life or the next.
