Your "friends" owe you more than they have given you, however, maybe as other have suggested they are telling you something. Actions often speak louder than words.
If you truly feel you are making the right decision and want to spend the rest of your life with this woman and her kid(soon to be your kids) then you are going to do what you are doing.
However, if there is even on iota of doubt in your mind, it may be the right time to take a step back and put the plans on hold until you are absolutely one hundred percent sure this is what you want to do. You have already experience on protacted and obviuously ugly divorce, why set yourself up for a second? Remember the only winners in a divorce are the lawyers.
