To suggest OH may not be good father material

[Timetable99]

Just that really. My OH is keen to have at least one child as soon as we can afford to but currently he plays computer games every spare moment he has (late 20s, no kids so lots of free time - he plays them a lot when WFH too) and he complains often whenever he does housework or has a busy social week scheduled that it is cutting into his gaming time. Busy to him currently means less than 2 hours available a day to do his own thing.
I pointed out to him that he would have barely any time to relax at all if we had children and that I'm not sure he would be able to handle how full on I've heard it is. He's upset with me now for implying he isn't good father material as he says he would get fully involved as soon as he has an obligation to be. I have severe doubts. AIBU? Is it possible to tell at all before committing to having children just whether the guy is going to actually pitch in and support 50/50?

Please remember this is a relationship not a prison sentence flowers. You don't have to stay.
This!!

I'm not saying people here are wrong or that he's perfect but the video game bashing on this site is incredibly snobby. It's a hobby and a past time like anything else and it's not childish. The issue is him doing it every spare minute of the day just like if he was spending that much time doing any other hobby.

As a woman who has always been a "gamer" and now works in the industry, the video game bashing is a cringeworthy uncomfortable read is all. I'm also a functioning independent adult that's the difference. Don't kill me

But yes if he can't do his fair share of what he needs to do now then I can't imagine it getting any better with a child.

A grown man who likes to spend precious time playing games on a computer is:

1. Boring as shit
2. Needs to do something useful
3. hasn't grown up.

Why would he change if he impregnates you?

You'll just end up with a baby and a whining teenager - him.

You've just moved in together, you know this is him at his best? This is him trying to impress you?

Because right now he sounds like a stroppy teenager with the first bit of freedom he has to do what the hell he likes. Honestly, he needs to learn to stand in his own two feet for awhile.

Oh, and someone who doesn't know how to be in his own head? Who is terrified of the boredom of doing nothing for even a few minutes? Who won't even talk to you when you drive to a hobby together? That's not a partner. And never will be.
