Is it normal to receive a lot of "eye contact" from a woman who's been in a long term relationship with a guy?

she could be bored or having problems in her relationship, so shes got the wandering eye syndrome. its possible shes bi or bi-curious. she could just like the attention she is getting from you but not wish to act on it. any of those alternate scenarios could produce jealous behavior. she might be into you though, so you should clear it up at some point.
