The simple answer to your question is no.
From what I read, the boyfriend owns the house, therefore he controls who can be on the property. You do not mention any rental or lease agreements, and without such, he can basically kick you out of the house immediately.
However, in light of your financial involvement, and property issues, I strongly suggest that you hire an experienced family law attorney to assist you in asserting your property and financial rights, and that you do so quickly so that you do not suffer any loss.
Now is not the time to look for ideas or help on the internet; now is the time to take appropriate legal action to preserve your financial and property rights.
I may be able to assist you, if you want.
