There are potentially two separate charges - criminal mischief for damaging the property IF it was your property alone (and not his property with you), and assault involving family violence and bodily injury.
Although you delayed in reporting the assault, the fact that you were treated in a hospital with a substantial injury makes it likely that the police will report to the prosecutors' office, and they will accept, charges for assault.
Because he is already on deferred adjudication, there is a likelihood if charges are filed that a motion to adjudicate his guilt on the probation case will also be filed. The burden of proof is much less on a motion to adjudicate than it is on the new charges.
The final outcome of all the charges is hard to predict because there are so many variables.Ask a similar question
