How are your bills and expenses split as a married couple?

Im 25f from the UK and am married to 32M. I am asking this question because I just want to know how others are splitting bills and then to also take a look at myself I suppose.

I make 25k working as a receptionist and struggling to get a better job that pays well. My partner makes 37k and his salary will be going up, he has a stable career. He works a lot of overtime to make more money as well.

My husband pays for all the bills, I moved into his flat. He pays for most of the groceries. I pay for some groceries and pay for electricity..he pays for electricity as well here and there. Im taking driving lessons weekly and pay 51£ for half and half. Also I'm studying accounting which im paying 60£ monthly for. I pay for my other personal expenses as well. I seem to run out of money as well. I save away money for both of us towards our first home. I put away 400£ and set aside 100£ for electric. My husband told me that he sends his mom money every month. She lives in the uk as well and has a working son living with her who pays for all the groceries and her partner pays for all the bills. Her asking for money from my husband seems to make us struggle but he said its fine since his pay will be going up. This bothered me quite a bit because yh fair enough he can send her money if she really needs it...but sometimes when she runs out of money she asks my husband. My husband has an older brother and he's also married with 2 kids and never sends my mil money and never has either. Idk if I should be bothered or is this actually my fault because I need to contribute more or something. My partner works a lot aswell. We don't go on weekly dates or anything either. We've been married for slightly over a year now and I might be pregnant as well need to test after next week. Husband said he's OK paying all the bills when I first moved in with him. I guess it's a cultural thing to pay for everything as man. I don't make enough though and it's such a struggle finding a good job. I've been trying and failing. I mostly do the cooking at home.

I want to know everyone else's opinion.

I asked my husband out for a meal today which I'll pay for on Thursday. My husband also mentioned last time that he never really spends.on himself when i asked about the situation with him sending his mum money. Before we got married he would send her 150 a month.not sure how.much right now..he sent her 40 this week for her knee pain acupuncture..he seemed abit hesitant but sent it anyway and that day we went out for a coffee instead rather than for a meal. He told me the night.before we should save.and might need the money. I was ok with it and then next day he sends.his mom 40 for her knee issue. Edit: i mentioned joint account in the past and his credit score is bad and also i think i spend more and earning less so if im honest..i.dont really wanna do that. I understand being married its together. I also do save away money for myself just incase in the future if anything happens.
