So me and my partner have been together 5 years now we have a son together he is 4 anyway to cut the point we had a few drinks and it lead to a deep conversation were I said you’d never be disloyal to me would you and he replied with ‘if I was unloyal I’d of f**ked the girl that messaged me early hours in the morning to go and meet her’ now this threw me back and I questioned what he meant who the girl was why I didn’t know about this like WTF he then told me I knew who she was and he wasn’t telling me who it was so obviously I carried on asking is disbelief that he’d even said this let alone kept it from me I’ve asked him multiple times for the truth as I see it so disrespectful that one I KNOW this women and two he’s hid this from me he said it was last year and he’s now left the house and said he wasn’t going to tell me who it was as there would be no point to it but it’s just playing round my head to think who this girl is and why he’s so protective of her and why the hell she would feel comftable messaging my partner like that when I clearly know who she is what do I do???
