Input: I'm UK based and get a certain amount of maternity and child benefit paid into my account. My partner works and our baby is his second child - his first born lives in a town not far away but he has to travel every weekend to see him. He's paid roughly £700/800 a month compared to my roughly £600. He works 3 days a week 2pm-9pm while I take care of the baby (he takes the night feeds as he's usually up until 3/4am anyway).

The reason I'm frustrated is this - we both pay £200 a month in rent as we're living in my families property. Beforehand I worked 6 days a week anywhere between 10 to 14 hours, paid our £600 a month rent, paid for the shopping and would give him money for the bills that came out of his account. Now I've obviously taken a step back, but every month when my money comes in not only am I still spending £100+ on shopping for the month and giving him half of the debt we're in, he's asking for half of all my pay because the baby is half his responsibility and he has to pay £10 a week in travel to see his first born.

I'm not angry with him and a big part of me thinks he's probably right, but it's getting me down that I can't afford to go out or do anything with my friends or the baby while he can afford to buy parts for a computer that he's 'building for me' that I didn't ask for and haven't used once.

The sentiment is so nice and our relationship is great otherwise, and he's a brilliant partner and dad to both his kids, I'm just... Frustrated.

AITA?
