You refer to him as your "ex-spouse" but also say that you were living with the father of your kids, so I'm not clear as to whether you were actually married. It makes a difference: if you were married, then the property title can be resolved in a divorce proceeding. If you are already divorced, that should have been addressed, so look at your decree. If you were not married, or if the property title issue was not addressed in the divorce, then you can bring "an action for partition" and have a judge rule that the house is yours alone.
