While it feels good to be needed and wanted, it's unlikely that you're emotionally ready to deal with a new relationship.
You will still have to deal with all the issues that caused the breakup of your marriage and make peace with the fact that it's really over.
So what should you do if you believe that this new man is the one you should have married in the first place?
You will most likely have ongoing contact with your husband after the divorce because of the children.
Dating during your divorce can poison the spirit of cooperation and affect your life for a long time after the divorce is final (and possibly after your boyfriend is history).
Another consideration that you should think about if you are considering living with your boyfriend is that it will affect the level of support you may eventually receive.
Even if you ultimately get custody of your children, child support levels may be lowered because you are living with someone and sharing the expenses.It can look like you have questionable morals, even if you were the perfect wife during your marriage.
