Might as well just be single.... help?

When I met my partner and for the past few years I’ve been so in love, loved his company etc and everything about him. We had a baby and she’s been amazing and he at first was a great dad, but I’m now feeling like he can’t be bothered anymore?
If she’s cries he instantly starts moaning and I have to take over, he’s too tired to do night feeds and changes apparently and constantly moans at me. Baby is actually starting to behave differently to him too which is sad.
I went away to visit family with baby for a little while, and I did everything on my own and I realised It’s a lot less hassle and I’m a lot happier.
I do find him quite irritating as he doesn’t really have anything to say anymore, he used to have lot of friends but even I agree he stopped making an effort so now he doesn’t and I know he’s annoyed that I still do see my friends.
When I was pregnant I was doing 40 hours a week and was the main earner, and when I go back to work I will be again too, he doesn’t 20 hours which is fine, but I know I’m going to end up doing all the baby stuff and house stuff anyway, so does being single really make a difference? I know I’ve got to think of baby but I wouldn’t doubt him not bothering with her, it’s like he’s suddenly realised she’s a lifelong thing.
Am I unreasonable for considering leaving him I over this? I do say I love him but every time I do I keep second guessing myself. I just feel horrible and like I shouldn’t complain. Any advice?

So he is home half the week and still doesn't help out?

How long did you know him before you lived together/had a baby? Sadly it's very common that people revert to type after a few years so this is probadly who he is.

I think it is fair to leave him over this as life as a single mum can be way easier. I found that people assumed Ex was helping so therefore I got less support.

It would be fair to give him a chance to correct his behaviour and as the baby is still young he could get more motivated as she gets older. Why does he work so little?

Yeah he is he tends to just watch tv or play games, and then go for naps because he’s tired. It’s pretty infuriating.
We lived together for 3 years before baby, knew each other for a year and a half before then. That’s what I’m thinking, I think I just don’t want to admit it’s a lost cause.
I’m going to give it a chance as I don’t think I could bring it up anyway, I’ve brought up issues in the past and it’s just ended with me apologising to him because he gets upset at everything.
Because he cant be bothered to find another job that’s literally it. My boss offered him a job and he couldn’t be bothered to go to the interview, he also won’t apply for anything no matter what me or family members send him. I think he likes not working much but the pay is awful and without me he literally wouldn’t be able to afford to live anywhere...

It's one of my biggest pet hates when single mums say "well you're not really a single mum because you do have a partner who can do xyz for you and you just have no idea." That's not the reality for a lot of couples. I had fuck all help from my husband/father of my kids, but he'd control what I could do with them and when. I've been a single mum 6 months now and although my kids are at really difficult ages and we've had lots of transitions which have upset routine - divorce, moving a long way away, starting school/nursery, me working for the first time in their lives - it's been the easiest 6 months of my parenting journey. Do what you want, how you want, when you want. Yes there are money worries sometimes but I had money worries anyway when I was with him on top of a load of other worries.

Completely not unreasonable to leave for that reason, I'd wholeheartedly recommend it!
