So I ended an abusive relationship last year (had a lot of support on here, thank you all), took some time and am now with another fella. We have agreed to be monogamous (no shady area there this time) but I have noticed when he opens his phone beside me that on WA I keep seeing a woman's name above or below mine in chats, so he must be talking to her quite a lot. He hasn't mentioned her and I know of most of his work and social friends, so I asked him who she is. He was on his phone at the time, so after a few second he passed his phone over and said, "there is no-one of that name on my phone," and it had gone, disappeared. Long story short, he has a) convinced me that I saw something else instead b) got angry when I challenged that c) is now behaving like it never happened. NB: My last B/F cheated on a dating app so I have form.. am I paranoid, or is this just too odd?
