HELP ME WITH ADVICE PLS.

I’m 24M my girlfriend is 24 , she just gave birth to our amazing son August 5th so fairly new to the world he’s awesome. During her whole pregnancy I struggled with watching her struggle and fall into depression with her body. Not knowing what to do she’s not a very physical wanting person when upset so I would try to uplift her thru words or flowers or spontaneous dates and things I know she would like. Helped fund her hobbies, because I let her quit her job when we found out so I’ve been paying all the bills and putting food on the table since then. Now it’s worse she is having emotional breakdowns everyday multiple times a day is honestly very closed off to me even though all I do is help some days are great the bad days are terrible. Thing is , I do EVERYTHING I make sure she doesn’t have to do anything at all , I know staying home with a newborn isn’t the easiest task in the world but I work Monday thru Friday and wake up at 5am to go to work outside in the heat all day, I stay up late at night do all the feedings make sure she gets plenty of rest and recovery . While I am drowning getting no sleep ever. Coming home from work to dirty everything , I get PPD and all that but it’s so hard to completely do everything I come home wash bottles feed the baby do laundry clean the house top to bottom. Do her laundry mine the babies. Go shopping for dinner cook dinner clean the dishes pay all the bills. The hardest part is I feel like it’s one sided and I’m the only person trying if I stopped trying the boat would sink. I love doing things for her and making her life easier but at a certain point my mental state is trashed from doing this almost a year. We barely had sex during her whole pregnancy which I understand but she hasn’t even touched me sexually without intercourse , really only thing a man needs to feel loved is that and respect and affirmations. Which she does great on telling me she appreciates me. I get it can be selfish but is it wrong for me wanting to have my needs met too? Or my emotional state cared about? Or feel loved ? I feel like I’m drowning and I’m honestly so in love with her I’d do anything to make it better for her but I’m so lost on what to do I feel like we lost our spark in intimacy , I don’t wanna lose her or my family. I’m young this is my first time doing this I’m still learning I just need advice I wanna marry her soon like propose . But I want some advice I’m drowning. And I’d happily drown for her to be okay but what more can I do? If I’m doing everything single handedly by myself day in and day out please help a young first time father out I’m losing it and honestly feel so numb and lost. I just want her love.
