WF - Just one further warning. When a person jumps from one relationship right into another one, there is the danger that the next one will be just as dysfunctional or worse than the last one. It really is important to take the time for self-examination and examination of the relationship in order to grow and learn.
Sounds like you would like to have a backup plan in case the marriage doesn't work out. Make that plan about you and your kids. I wish I had done that. I jumped into a second marriage and now have to deal with stepkids, custody arrangments, ex-wife, child support plus the quilt of not knowing if I did everything I could have in order to save the first marriage. I bailed out of fear and desire and latched onto what looked like a life preserver. It actually turned out to be an anchor and the weight of it all is enormous.
