Are you willing to wait it out in the same house until next summer? Is that going to be conducive for your emotional and mental sanity? Can she move out? I would look at these questions to see what you should do.
If she says she needs space and time to heal, then you have two options - ask her to move out or you DB like TxHubby if she can't move out. I don't really see any other option for you where you can maintain your sanity.
If she has said she needs space, validate her feelings. But, start at looking how that can be accomplished that works for you.
