Does she like or am I going nuts?

So there is this girl works in my community i am part of and whenever I talk to her when she helps me out with stuff she is always twisting her hair or throwing it back on one side. She even laughs at most of the stuff I talk about but the crazy thing is she married and has two kids. I honestly can't tell if she's just being nice or if she likes me I have no idea.
Does she like or am I going nuts?
