long story so i'll try and keep it as precise as possible.
i have a friend who i've known for around 5 years through work. we had at one point a fairly tight knit friendship group of a few of us who worked together, which unfortunately fell apart due to her falling out with everyone in the group (bar me) over the years. it was all about silly little things (in my opinion) that got massively blown out of proportion, but resulted in me being the only one still in contact with her as i never saw a reason to not be.
everyone would always make jokes about her "fancying" me, due to the fact that she'd always causally make remarks about being "in love" with me and often subtly (and i thought subconsciously) copying me in terms of what i wore and that kind of thing. i thought nothing of it, she knew i was happily married and got on brilliantly with my DH.
anyway, last night i was at a party and whilst i was there i got talking to someone i knew who'd formerly been friends with her as well but, not surprisingly, also ended up falling out. she made an offhand remark about "not expecting you and her to still be close after the whole DH thing" and obviously i demanded to know what she'd meant. they looked taken aback and just kind of went "it's probably just another of her lies, it was ages ago" but eventually told them that this 'friend' had gone around telling people my DH had sent her 'innappropriate texts'.
i immediately texted my friend and brought this up, to which her response was "i can't remember exactly what but we were just chatting like normal and he kept making sexual innuendos" so obviously i called DH and told him to explain himself. he swore it was all lies and came to pick me up (i really didn't feel like staying longer) and let me check his phone. they barely spoke over text anyway and there were no texts of the nature she'd sent, and when i texted her this she claimed he must have deleted them and that it was years ago anyway so 'didn't matter'.
at this point i was obviously quite upset, so DH (who has never been unfaithful or given me a reason to believe that he has been) said he'd text her himself, his texts wouldn't deliver so he went to try on whatsapp and then fb message her but she'd blocked him on both - there is no reason for her to have done this as they'd never fallen out.
my other friends think she's lying as she has a habit of lying about a lot of things (she's falsely accused people of sexually assaulting her before for example) and i believe my DH but i still can't get what she's said out my head and i want to message her saying so but i'm not sure what to say.
any help or advice would be so gratefully received!
