If I filed for separation last week, am I financially protected even though my spouse hasn’t been served?

I was worried I would owe alimony if he quit his job so I filed for separation to protect myself. We discussed the terms of our separation and he's made it clear he will dodge service. Am I still financially safe even though he refuses to be served? I paid the fee and filed all the right papers and just want to make sure I'm protected for the time being until he gets served. I pay most of the bills and can't afford to pay for an apartment in addition to the mortgage and he refuses to move out so we're still living in the same house. Is that a problem?
