STRESSED OUT!!!

Is anybody else stressed out with their partner and just needs to vent? My fiancé  is pissing me off to the point where I'm ready to leave him for good. I've never been so stressed out in my life and this is a time where I feel like he should be there to uplift me and make me smile. As pregnant women we go through so many changes, opinions, anxiety, etc from pregnancy alone the last thing I need is to be stressed out by someone who I look to for comfort. The other night we argued about not having sex but I'm TIRED!!!! Like extremely tired and I don't have the energy for it or just simply not at all in the mood to have sex I don't even want to think about it. I feel like he wanted this baby so bad but doesn't want to take the good with the bad. He stresses me out about EVERYTHING!!! I'm so ready to give up on this relationship because it will only get worse before it gets better. Smh!
