I have been seeing my ex again recently. In the past week I have seen him four or five times and sleeping together. We haven't had a conversation about 'what' we are or our relationship status.
On Tuesday we had made plans (he had asked me if I was up for doing something) and he cancelled saying that he had a lot of work to do and the gym.
He turned up to my house today with scratches on his back, he said that they were from scratching his back but I was suspicious. To be fair to him, I have seen him scratch his own back in the past and leave red scratch marks like the one today.
I had a gut feeling he had slept with someone else on Tuesday when we were meant to meet and I asked him, he denied it. I said it was his last opportunity to tell the truth and he admitted he had slept with someone on Tuesday.
He said he knows how it looks but that he doesn't see me as second best or choose me over her, and that he had cancelled on her twice before to see me and she wasn't free for the rest of the week.
I got upset and politely asked if he would leave as I didn't feel like spending time together anymore. There was no argument or anything like that, all very calm.
He has messaged me apologising again and saying it isn't how it seems.
We aren't together and haven't had that conversation yet.
So AIBU to be upset?
