"I keep calling him 'my husband,' " she tells PEOPLE of newlywed life. "It's awesome!"
Fishel, 32, also shared one of her favorite (and private) moments from the big day on Oct. 19.
"Tim and I went into the reception room before all the guests were let in," she says. "When I saw how beautiful it was and all the hard work I had put into it, my breath was taken away. Tim and I danced alone on the dance floor for a few minutes. We took it all in."
And the actress couldn't help but shed a few tears before the ceremony.
"I started to cry when I first started walking down the aisle," Fishel says. "It's hard to prepare yourself for the amount of love you feel in that room. I felt beautiful."
The reception was held at LA's Vibiana – decked out in Old Hollywood style – and Fishel was reunited with Boy Meets World costar Ben Savage and Home Improvement's Jonathan Taylor Thomas, with his date Emily Craft.
The happily married Fishel (who will use Belusko personally), is ecstatic about her new journey. "This is my family now," she says. "We're in this together."
