Name changed for obvious reasons. Has anyone ever found them really tempted by another person and how the hell do you get out of it/past it. 
Things haven't been great with me and DP for a while but I thought we were on the up. In five years I've never had my head turned apart from one person I see professionally who I am ashamed to admit I have fantasised over, but I have never gone further than pure imagination although I did suspect the chemistry could be mutual. Said person, who is in a position of control over me, has now started contacting me in what feels like a flirty manner and I don't know how to handle it. I feel like the worst person ever for even thinking about it. But I'm imagining what my life would be like with this person which is completely ridiculous! Please help. Is this a sign I should leave my partner?! I just don't know what to do with these feelings. I can't stop thinking about him and I hate it.
