3rd trimester bs

I’m 31w4d and I’ve been randomly over emotional over the dumbest things and even normal things but they just get blown out of proportion and I feel bad for my bf but he starts them half of the time and I try to express my feelings to him but I start crying so the only way I can get my feelings across is to txt him an essay! Ughh and at the same time I feel like he doesn’t actually hear me when I speak yet i push myself until my ankles r super swollen and my back is screaming just to make sure the house is clean and kept up. Yet he makes stupid comments when I do not feel like having sex after a long day. Ugh I apologize for the patchy rant I just needed somewhere to vent. If u read thru this whole thing thanks for listening
