Backstory:
DP and I split over a year ago where he spun me a line "I love you just not in love with you" he then proceeded to tell me everything was my fault. Not enough sex, I wasn't who I used to be, I was selfish. He changed his attitude when I started dating and suddenly seemed to realise that he had lost the best thing to happen to him (his words but I have to agree :P ). I wasn't having any of it at the time. The relationship I was in naturally took its course and we mutually decided we weren't right for each other. DP then stepped up a gear and wanted me back. I agreed top try again and work on our problems BOTH of our problems. In the time we had split he had miraculously started dating a girl from his work. I found out he was still sort of seeing her whilst we were trying to sort things out and told him that he was being unreasonable and if he didn't tell her I would. He didn't so I did. we then split again as I couldn't trust him.
At the beginning of our breakup I missed my period for two months which was then proceeded by a horrendous one that was (sorry if TMI) clotted and extremely painful. I never took a test so I will never fully know but my gut was telling me it was my worst nightmare. I still don't know if I would have preferred to know or be in this state of confusion. It still hurts to this day. After the second split, we agreed to sit down and talk I told him what I had been through on my own. I didn't know how to deal with the emotions I had so I shut off. I realised what I was doing and tried to let him in again but by this time he was acting weird around his phone. If he saw something funny when I asked to read it he'd send me a screenshot, would turn his phone away from me when sitting near me.
Anyway, fast forward to today. A friend of mine told me she'd seen him in a town near where this OW lives that shed seen him with a woman who matched OW description. She doesn't really know the backstory is a friend at work and would have no reason to lie. So I told him that my friend had seen him in said town (no mention of OW) he denied it point blank but was really shifty and gave far too much detail about how it could have been him going to the gym or how he sometimes parks near there. I'm not proud of it but his wallet was lying around and so I snooped, I found receipts for pizza express and other places in that town. He had been there, I confronted him today saying if he had nothing to hide he wouldn't mind showing me the receipts. He wouldn't show them kept denying he'd been there. I told him he had one chance to tell the truth or he could leave. He started to go through the receipts but hiding some in his wallet as he pulled them out wouldn't let me hold them and kept reading them and putting straight back in his wallet. When I mentioned the OW he said he'd seen her twice but only told me one of the times hed met with her which was to give back her stuff. When I asked him about the second he changed subject, actually accused me of being paranoid.
So I told him he had his chance to tell the truth and he didn't take it. I was sick of his lies and he can fuck off. My DD and I are perfectly capable on our own.
I needed to rant sorry its so long but could anyone advise me re how to handle it with my DD?
