Visitor Visa - B2

I'm a Filipina. My husband (domestic partner/we're not married), is a US Citizen. He was an active US Airforce from 2000-2006 and reserve until 2008. Now, he's working in the US Embassy Manila. We just registered our son to a US Citizen last month. We are planning to have a short trip in the US, in CA to be specific. I would like to give my son a chance to meet his dad's family and spend his 7th birthday there as I wasn't there when he had his 6th. I want to give him the best birthday of his childhood. Bring him to Universal Studios, Disney California Adventure Park and others.. His will be sponsoring me for the tickets and other expenses will be shouldered with his family. I'm currently working here in Dubai.

As for my ties, I may not have all the material things that they maybe looking for. Though we have a house and a Toyota Hilux registered to my husband. My immediate family is in the Philippines. My father is turning 84, and currently suffering from Alzheimer's disease. As soon as I'm done with my 2-years contract here in Dubai, I will be moving back to Manila to be with my dad.

Is there any chance for me to get approved for a B2 US Visa?

Thank you.
