Right, sorry if I waffle on but here goes!
Sunday night DP came home at ten pm after going out at 2pm, saying he was going for a couple of pints but would be back in time for dinner, so when he rolled in I was already pissed off. He went out to the garden and I could hear him on his phone, chatting and laughing, though nothing of it but then could hear very distinctive flirting chit chat, so I went to the door and listened and could hear obvious sexual chit chat. I listened for a couple more minutes before I flipped out and stormed into the garden and told him he's a nasty cunt and to get some stuff and get out. He looked shocked and immediately put phone down, and started to lie that he was talking to his male friend, I said prove it and said I had been listening for 5 minutes so he admitted it, saying it was just flirting and then the shouting row began. He refused to leave and I didnt want to wake DD up so I went to bed and told him to sleep downstairs.
It's now Tuesday and I'm feeling stupid and he can do nothing but apologise. He said they have always flirted, but nothing has ever happened, they have known each other for years.
How do I trust him again, I hate feeling like this :-(
What should I do?
Thank you for reading!!
