So this won't be the most popular response, but I'm going to say it anyway....wanting to force ANOTHER marriage on your children is extremely selfish. The older ones have already gone through two traumatic divorces. The last thing they need is to try to merge your families together and be one big happy family. To attemt this is one of the most selfish, thoughtless acts you can do. Both of your priorities should be the well being and peace of your children. To say children are resilient and will adapt is a cop-out. Of course they will adapt in some way, only because they have to. Your children should come FIRST, not your desires. Divorce among couples who merge families is way higher than the average divorce rate, because loyalties to ones own children supercedes the loyalty to your new spouse, and his/her children. Going into such a marriage with the children on both sides ALREADY upset and protesting ensures disaster. Stay single until your youngest is 18. Show them THEY are your priority, and stop the drama in their lives.
I'm sure this will fall on deaf ears, but I felt a need to say it. Be angry with me if you will, but when you calm down, think of who is really important in this whole situation.
