i been marry 15 years have a son 21 years old my husband never live in my house do i have to split the house ?

What's really important is how the house is titled and what money you used to buy it. If the house is titled to you alone and you used non-marital funds to buy it, you may be entitled to keep it. It's a touchy area of law, however, and one that should be approached with caution.
