So this is an AIBU/am I overreacting?
Let me set the scene.
Partner has always been shifty with his phone, for example, angling it away from me when sending/reading messages and quickly putting it away in his pocket if I come across him using it etc.
In the early days he lied about deleting all of his WhatsApp messages from his ex, claiming that she must have deleted them all her end. I pointed out to him that I'm not an idiot and I know how deleting messages work. He then said it was for me because she has written some unpleasant things about me and he was considering my feelings...
So last night he went for a shower and left his phone on the bed unlocked and open on messenger and I saw his contact at the top (so most recent)was a woman that I'd never heard of so I looked (I know it's an invasion of privacy etc but 🤷) and saw that he had arranged to meet her last week but cancelled last minute claiming he had covid. I asked him who she was and he said she was an old work colleague and she asked him if there were any jobs going where he works now and she suggested going for a drink to talk about it. Funnily enough, if anyone else asks him this, he tells them to look on indeed where his workplace posts vacancies. Honestly, I don't think she's an old workmate, I think he met her on a meeting site or some such thing. He definitely had form for this before we met. He also has form for lying and will happily die that hill if he's caught out being less than honest.
I realise that he didn't meet her, but that doesn't change the fact that he had arranged to in the first place. I'm furious and basically done with this relationship at this point, but I'm now wondering if I'm overreacting. I can't get past the fact that he made plans to meet up with another woman.
