Hi there Ali - for what it's worth - this sort of action isn't confined to men! I had a pretty much similar experience with my ex-boss - who I found myself getting a lot of validation from - concerning work I might add, at a time when I was low and feeling more and more remote from my W who, rightly was consumed by our then baby son...
Some months later, after I left my job cos I was feeling that things could get a little too uncomfortable with woman pretty much told me that her aim was to get me into bed and that she was sure I wanted her too...
I didn't...and I have hardly spoken to her since.
But I don't think these people are inherently lax in their moral outlook - just vulnerable themselves in the main...
I feel absolutely sure - its nothing to do with you - nothing that is flawed in you...
Best - GFI
