Help!! A Married Woman is in Love with me

I don't intend to bore you with my bio n stuffs, just straight to the point. I attend a church and belong to the Security Unit; Altar

Sector precisely (those guys that stand n face the church with radios plugged to their ears from beginning till the end of service). Because of my appealing face, I'm always chosen to be in front which is very close to the choir stand.

However, I have this lady in the choir, she's married but childless, we started speaking some weeks ago. We happen to start speaking one Wednesday when I had to drop her after service.

Fast forward, she calls daily and stuff, I got to know that the husband is impotent and she's the one that got him his job. Deep down in me, I do not want anything to do with her, but she's always calling and asking for dinner at her place or mine. I recently (today)also got to find out that the husband has been out of the country for 4 months now.
