Name change as have relatives on here.
Used OH phone tonight to message someone.
On his WhatsApp found messages between him and a mutual friend (F).
Have nothing against platonic friendships btw.
These conversations go back a while. At least 2019 from what I can see.
Many of these messages are flirty and sexual innuendo type ones.
Good morning/night messages everyday.
Kisses on every message.
We are talking 10s of messages a day.
Inside jokes and nicknames.
No photos.
Some have bitched about me, my mental health etc.
No mention of meeting up etc l, although they used to meet for coffee a lot pre covid.
I've tried speaking to him, he says she's his best friend and understands him, that's he's done nothing wrong.
AIBU that I think somethings going on and I'm in the right here.
