2nd marriage problems - just as first marriages, second and subsequent marriages have problems. Marriage is the union of two different people, joining to live as one person. How can there not be problems? Just because there are problems, though, does NOT mean that they can't be resolved! Life is full of problems - it is also full of solutions to those problems!
Does your new spouse have children from a previous marriage? This is true in a lot of second marriages. If so, you have to accept those children, and be willing to raise them as your own.
This also means that your spouse has ties to his ex wife (the children's mother). You also must be willing to deal with this bond that they have. This will alleviate one of the most common 2nd marriage problems, right from the start.
An easier way to do this is to know that your spouse is married to YOU now - your spouse loves YOU. The only reason they still have ties with their ex is because of the children.
Are either you or your spouse bringing old debts into the new marriage? You should decide, from the start, who will be responsible for those debts. You or your spouse alone, or together. This will put a halt to any arguments down the road regarding this matter.
You should have a living will. If you have kids, they could be left with nothing if something should happen to you, and you don't have one.
As with all marriages, communication is crucial to your marriage. Talk to your spouse - listen to them. Share with them, and let them share with you.
Don't bring any negative things from your past with you to your new marriage.
