Partner doing constant overtime

No. I had to have a conversation with my husband about this. We have picked a day that is a family day and he doesn't work on that day and neither do I. It doesn't matter if we are sitting around the house or going out to actually do something but we are spending all the time the kids are awake with them and the time they aren't we spend together. This bonding time is important. I would approach this in a different way. I would tell him that all the extra hours he is working is making you feel distant and alone like you and your child are less deserving of his time. It isn't what he intends to do but you need a day a week that he will either spend with both of you. It's important to us staying connected through these big changes as a family.

Have you ever wondered if he’s having an affair? just thought this from personal experiences sounds very similar xxx

it’s such a difficult thing isn’t it, but everytime I try and talk to him he just kicks off and I try not to argue with him but at the moment I’m going though some health issues that I’m getting tested for aswell it’s just so much added stress and I genuinely feel like he’s not there for us. I can’t help but feeling like he’s avoiding me

I'm a blunt person. I would tell him the constant late nights, the avoidance of an actual conversation, choosing not to be home with his family at anytime. It all leads me to think you might be having an affair. Do we need to look into couples therapy so we can have a conversation? Or are you already bailing out of this marriage?

If he tried to make it into an argument I would tell him his additude feels like he's already bailing out.

I can put my emotions aside for the conversation though.
