Me and Mary Regan

I have decided to give up with Mary Regan. She never phones me. She ignores most of my texts and emails and just when I am forgetting about her, she contacts me and tells me she loves me. She says she can't chat with my on Facebook or reply to my emails because her boyfriend is intensely jealous. What I want to know is, if she loves me, why is she still with him?

Or, does she just say she loves me every now and again to keep me on the hook and keep my adoring her and sending her flowers and poems and things?

Any advice from a woman would be welcome as women are not like blokes and will be able to advise me about their hard hearted bag of tricks to keep men broken hearted.
