Thinking about divorce

Me and my husband have been together for three years married for three months and we have a 2 year old. Since our son was born it feels like we lost ourselves and everything's about finances and baby. I don't get much help from him on anything. I do all the cleaning, taking care of our kid, all the appointments. You name it and I've sat down and told him I need more help that I was becoming depressed and stressed out. Says he'll change and he does for two days and then switches back. We have fights over not getting child free time, me having friends over, him never taking our son when he hangs out with someone. Struggling to get him up to spend time with us instead of sleeping until it's time to go to work (he works nights) so we get maybe two hours and that's spent taking a shower, cooking or sitting on his phone. It just feels very distant I've been feeling like a single parent. Complained I didn't have a job that I didn't know the stress so I got one and still did everything. There's so much more but I have tried just about everything. I've tried telling him how I feel and he just turns it around and tells me how I'm wrong or how it's worse for him. I try waking him up but he doesn't get up until he decides. It's like pulling teeth to get him to do much like change a diaper, wash the sippy cups, do laundry, let me have a few hours to myself, letting me shower. I have to ask for all of this mean while he just informs me what he's doing. I've know I haven't felt happy for a while but wanted to push because of our son and lately I've really been thinking about divorce but I'm scared to start over, scared I may make the wrong decision even though I feel like I've done everything I can. I've just reached a point and everyone knew it was starting to build up. Should I feel horrible for wanting to leave?
