Why is EVERYTHING my job?!

Ok I get that my husband works 6 days a week and I get he’s tired, but my freaking god the in past 3 weeks he’s had 3 and almost a half days off and he hasn’t done ANYTHING to help ME with OUR home. The things I physically can’t do he refuses to do. He jumps to help his dad but even when I beg him to help me he refuses but during arguments he reminds me that it’s his house and he’s the man of the house. He talks about building his own house one day and teaching our son this and that but how the hell is any of that going to happen when I can’t even make him coat a freaking roof that’s been leaking off and on for MONTHS. I get he is tired I get he works hard but my god, today I worked so hard to clean I had sweat pouring and I’m pretty sure I started to over heat. I don’t want to use pregnancy as an excuse but my god! I cut the grass yesterday, moved stuff I asked my husband to move, cleaned the porch, and today I pretty much got the entire house clean and my husband started bitching because he lied to me last night when he said he’d help me with ONE THING today. Guess who ended up doing it? Me. I swear I just feel like everything is put on me. Now all he does is go to work, come home, sit down and watch tv and eat and get up to pee or something. He does absolutely NOTHING. He’s cut our grass ONCE since we bought the weed eater and I had to ask him to do it but he jumped at the chance to help his dad cut grass. Why am I being put on the back burner? Today I went to lay down after working and I was tired and re came to our room and started touching my boobs and my butt wanting sex. He feels like he deserves it. I just feel so freaking alone and like I’m expected to do EVERYTHING. I’m sick and tired of it
