No matter whose name is on the deed/mortgage, until a final decree of divorce is issued, or legal separation agreement is entered, into that specifies which spouse has the rights to occupancy, you both have equal rights to live in the house. The reason is that, at least for now, it is still considered to be the "joint marital residence". Therefore, your husband cannot evict you or change the locks, etc. At this point, you should contact a local divorce attorney and consult with them. They can best advise you further.
