Hi OP. You’re in similar territory to where me and my stbexh were in. ReadI gotta this thread has reminded me of how much shit I put up with - lying, criticism, being taken for granted, dining out with female colleagues but zero effort into me/us, no affection unless wanting sex; if I’d object he’d then start criticising me; gaslighting. You name it. And there is more too.
Reading this thread has been a useful reminder of why we are now separated. It can be easy to minimise behaviours because you will be so invested in your family and your marriage and you will want things to work.
We did a year of marriage counselling. One last try. We still didn’t make it work but at least I know we have our all. Would your husband be willing? The problem for me is the lying. My ex did this too and for very similar reasons - not because he’s trying to spare your feelings or protect you, but because he’s trying to protect himself from your nagging. He basically wants to have his cake and eat it. Now I’m not suggesting there’s anything going on with the other woman but he knows that you’d be upset so instead of addressing why you might be upset, he has chosen to lie to you. There is the issue. He prioritised himself and going for a nice little pub lunch over your feelings. That is very selfish and indicates that he has lost respect for you. He may have checked out of the marriage.
What to do..? You can confront him with the bank statement, watch him squirm, etc. Won’t make him respect you or suddenly make him see the error of his ways. I’d let him know that you know he lied. Then his reaction will be telling. If he’s remorseful then perhaps you’d consider marriage counselling. If he becomes defensive and tries to gaslight you even more then I really think you need to consider cutting your losses.
We spent £100s on the counselling. From the start and right through to the end my ex insisted that I’d basically forced him to lie. Looking back, he was emotionally abusive and, though the counselling helped in some ways, it was never going to save us.
