Hmmm.........can she really be a???

Okay, here is the whole story. My cousin is a lez and she thinks her co-worker like her because her co-worker Natalie comment on how cool my cousin Angela looks with her sungles. In addition, Natalie always go up to my cousin and start up any conversation she can come up with. When they work together Natalie just call out my cousin name for no reason and smile to her. However, the main key in this whole situation is Natalie has a boyfriend and a daughter. Can she really like my cousin or she is just being friendly? Anyone has some opinions? thanks!
