Just need a bit of guidance as I'm in a real situation here. My boyfriend and I have been living together for 4 yrs, we knew each other for about 4 years before that. We are both in mid 40's and have a child each with another partner. I'm totally besotted with him, but can be moody and a bit moany as I work full time, have my daughter with us (who is great I may add) - what with work pressure and me managing tight finances, I am sometimes stressed out. He always tells me how much he loves me, he'd marry me tomorrow and he does everything for me, I honestly cannot fault him and adore him. However, a few days ago I looked at his phone (wrong I know, but it was there and for some reason I just wanted to look) he was still asleep upstairs. When I opened the phone, he'd been using messenger (which he never uses) to text a woman at his work - she's much younger than him and he'd started to lead the conversation down a route that was (in my opinion) way out of line. This was at 1am and I'd gone to bed at 10.30pm. He was drunk and had messaged family members and friends too, but had got talking with this woman as she'd said what a nice 'wave' he'd sent her, so he was then telling her how he was so pleased to be talking to her out of work hours, and that she was known as 'pretty [name]' from the office and that she always looked absolutely blo*dy amazing and that she was sexy and if she was single and she should ask him if so, then asked why she was single and said he'd be the luckiest bloke when she got together with someone and that he was always happy when he bumped in to her as she made his day brighter, with a love heart. then the following morning whilst I was looking - she messaged him and asked if that's why he stands in a particular spot when on his cigarette break to watch her walk in and out of the office! What am I to think? I've thrown him out, as to me - it's cheating and I'm devastated and heartbroken. He's been messaging constantly over the past 4 days begging me to realise that it's because firstly, I was moaning and moody so he wanted to boost his ego, then it was because he was paying her compliments nothing more, then he's apologised and said he was just drunk and it meant nothing, then he's admitted he was flirting and shouldn't have said those things, but it's not relationship ending. I feel totally devastated and sick to be honest. Has anyone else had this experience - I thought I could trust him completely, seems I was so wrong. :(
