Why do I deserve so much misery and no fucking help

I’m at breaking point with a 10 month old who never sleeps and a baby dad/ “partner” who is useless Tonight he was meant to come over but it was then too late for him, ( long story short he’s staying with a friend as it’s “closer” for him to get to work but I found out he’s working 20 mins form here..) LIAR) I deserve help at night he’s off all day tomorrow and she doesn’t sleep he just can’t be bothered to help He sees her 1 day a week for 10 hours maybe, Even on Mother’s Day he forgot and had to go to the shop in the morning and get me some half dead flowers and some chocolate I don’t even like I’m so fed up but without him I’d be screwed financially I have nothing only uc which leaves me with nothing 2 weeks after getting it if I’m without him Life fucking sucks
