Will UKIP send me back or make my life difficult?

Hi,
I'm a Latvian citizen and have been living in the UK since 2008. I've been working and paying tax since then. I happened to fall in love with a British citizen and married him in 2013. Now we expect our first. We also applied for a mortgage.
My question is what will UKIP do to me if they win European and later, General election? Will they make my life difficult or even deport me?
It seems like more and more people are willing to vote for UKIP. I understand that some people who abuse the system shouldn't be here but what about people like me? How UKIP intend to draw a line between me and immigrants abusing the system? How will they see who is who? Or just not to bother and deport everyone?
Thank you
