I should say there is a long backstory to this that I have posted about before but I will try to summarise.
Last year I became unhappy about my DH closeness to a female colleague (going out just the 2 of them, the cinema story if anyone remembers) and doing things for her, like helping her move when she split with her husband. I asked if I could see their messages but he wouldn’t show me which made me more suspicious. I later looked at his work phone, which I know was probably wrong but found some flirty messages, I then told him I wanted to see his personal phone messages which he got angry about but showed. There wasn’t anything directly bad but a lot more than I realised and I didn’t like the timing of them.
We eventually sort of moved on as he said he would take a step back and not go out with her any more but wouldn’t ignore her and say he was busy so couldn’t go out.
I know it was probably wrong of me but I checked his phone again a few months later as I wanted to see if he was telling the truth. I found he had bought her a birthday present and not told me as well as some other things he’d done for her.
I was angry but didn’t confront him as I was worried about his reaction. I made enquiries about divorce and universal credit.
He has now found that email and was upset about it. We had a calm conversation about it, I tried to explain to him that by buying her a birthday present after telling me he had taken a step back and hiding it from me felt like he was prioritising her feelings over mine. He must have known I wouldn’t be happy but chose to do something to make her happy instead. Also if he hid this what else might he hid. There are other things he’s done for her as well, some of which he deleted the messages. He didn’t really have an explanation for buying it, and didn’t seem to think he had done anything wrong. He thinks I’m muzzling him from doing what he wants. Which I suppose I am but he told me he’d taken a step back then does this. How am I supposed to trust him without any accountability? I know there are faults on both sides.
sorry it’s long. I don’t know if couples counselling would help.
