Divorce road or pregnancy hormones?

TIa
I've been complaining that my husband has become lazy and inconsiderate lately and that he's changed since I've been pregnant but then it hit me. What if he hasn't changed at all what if it's me that's changed? Maybe I've never noticed the lack of romance or laziness because I didn't feel like I needed to feel wanted before I felt like a fat cow and maybe I didn't notice the laziness before because I actually had the energy to pick up his slack. I feel like something has changed and I don't know if it's him or me but I don't want to start our family this way and I'm to the point right now I'd just wish he'd stay with his dad until the baby comes because then at least I'd only have to cook and clean for myself and not him too. I can't believe that I'm thinking this way I should be so happy and now I'm thinking about divorce. Should I wait a while longer to make a decision, wait for my hormones to settle or should I make the decision now to get out before the baby gets use to having us together.
