Aibu to not buy a cooker if I have a child to cook for?

[Jojorichards]

I split up with partner a few months ago and just moved into our house just two of us.
I won't lie its cost a fortune and just paid £800 for carpets.
At the moment I can't afford a cooker so I've bought a mini oven with grill and 2 hot plates all powered by electricity.
Both of those was only £65 and I can cook a roast/cake/fry a egg/pasta ..basically everything you would want to cook can be done.
My partner came around to collect our child and sneered at me for not having a cooker,as if I was neglecting our child.
Please tell me I'm not being stupid?
Il try and upload pics of what I have.
So far I've cooked a roast ,Victoria sponge,fried breakfast,pasta.

I had them when I lived on a bedsit many moons ago as did most people in their first homes. They're fine

I wouldn't be in a hurry to get a normal cooker. The set up you have is perfectly adequate, and as a pp said, the oven will use less electricity as it's smaller. Also, if you get a cooker when you get paid, your ex will think you've done it because he said you should. Don't give him that power.

We lived for nearly a year with a counter top oven as we couldn't afford to replace our main oven. (Hob still worked). I successfully kept 3 children alive the whole time! The only thing I couldn't do was bake a decent birthday cake.
My mother was horrified and eventually bought us an oven because she couldn't understand how we coped...
I still use the counter top oven loads, it's dead handy
