Thinking of leaving my partner

[Anon1623]

Hi. Sorry this might be a bit rambling..... I've been with my partner 6yrs and we have 2 beautiful daughters. I'm so happy with the girls but find him so difficult to live with. I'm the main breadwinner and we both normally work full time ( I'm currently on mat leave). I own the property (mortgage) and have done since before we met. He pays me rent of about £500 a month that is where he feels his responsibility ends, except splitting nursery fees.... I pay for everything else and any unexpected expenses I have to fix... I'm not so bothered about the money it's just his attitude that he's in charge of the household and I need to tow the line more. He keeps having a go at me about doing more housework and why should he have to do it at all. But I find it difficult with one toddler and a baby to look after. Also telling me that I'm not being a team player etc. I've had to save up hard for my mat leave because he won't contribute more even though I'm not earning at the moment. I'd understand if he didn't have any more but he just used the extra to get a tattoo sleeve done which cost ££££ and got a new credit card and maxed it out on pointless stuff for himself. When I met him he didn't have anything and I've helped him and got him to re enrol on the course he said he'd always wanted to do but he's lost interest and even though he's paying for the course he's not completing it. He's also started so many odd jobs round the house but never finished them (my fault for not buying materials/ keeping the place tidy enough for him to finish).... Complaining he didn't have enough money for Christmas presents so I gave him£100 and he got me a £100 voucher for Christmas.... could go on for hrs! It's kind of comical really.
My friends and family have stopped coming round cos they can't deal with the way he talks to me and just ignores them. The most upsetting bit was when he started getting our 3 yr old to say look there's mummy whenever a elephant or hippo was on TV. And I'm not huge! He totally didn't understand why I was upset and told me I was being miserable.
It's difficult because it's not so clearly awful that I know I have to leave. But I feel myself getting lost. I've tried to finish it and he gives the I've got nowhere to go, you're taking my kids away from me etc and whenever I try to tell him why I'm unhappy he says I am being stupid and my problems are completely unreasonable and pathetic.
He loves his kids and he's not an awful person. He works hard, but never wants to take me anywhere. There is no romance. He just thinks I'm grumpy.
I just need a bit of a sounding board... Am I being unreasonable?

Thanks for all the support. Hes just spent so long telling me that I'm being unreasonable that I'd started to believe it! Not wasting any more time..... Xx
