Wanker DH has spent over £300 on a computer to play Pokémon

I hate this man child.

He won’t even let DC play on it.

If you are married, it's not 'his house'. Divorce him.

Yeah I don't think gaming is your real problem. Call a solicitor and start filing for divorce.

If you want support you need to explain the actual issues. Raging about something he’s done without addressing the situation isn’t going to help.

Time to get your head out of the sand and working how you extricate him from your life.

was she expected to babysit whilst you did all of that?

It's not "babysitting" if it's your own kids. That's the sort of nonsense men come out with.

Yes, as though they're doing you a favour. That's why I asked in that context, as though the OP was a man and expecting the wife to 'babysit' so he could go doing all those hobbies.
Just because a woman objects to a man doing some hobbies doesn't mean she's controlling, sometimes it's because the other partner isn't pulling their weight.
Leaving someone because they didn't want you to do something you liked isn't always a reflection on them.

It isn't "his house" it is a marital asset. If you want out of the relationship you need to start divorce proceedings and the house will be split along with everything else.

To your first post, if the money is available and nobody is going without, then I cannot see any reason why he should not buy himself a new computer and games.
