Dp is in sporadic contact with an ex of his from several years ago. They used to speak occasionally, via Facebook, until she moved to a different part of the country and they didn't speak for ages.
She moved back to near where we live last year and since then has been back in touch with Dp. I'm fine with him talking to her as I trust him and he is very open with me about talking to her and what she says (I don't ask, he volunteers all the information!).
Recently however, he told me that she was asking him for favours (lifts, etc) and had been offering him blowjobs and sex as 'payment'!! Obviously he declined, but now I'm a lot more uncomfortable with him being in contact with her. I'm also pretty angry with her as she knows he is with me, Dp has been discussing our upcoming wedding with her in some of their conversations!
Wibu to message her and ask her what the fuck she is playing at maybe gently remind her that it is inappropriate to be offering sex to another woman's fiancé? And warn her to back the fuck off politely request she doesn't do so again? Or should I just ignore and leave Dp to deal with the situation?
