Long but NEED some advice so if you like giving it then please be patient and read. Here's the jist of it; I usually am very mommy like (even when it comes to my hubby) always doing everything for him and so forth. He's very capable and doesn't demand it but he works hard all week and I don't so I don't mind. Sometimes when he's in a "mood" if I ask if he wants seconds or food he makes snarky comments like "I can do it, I'm a grown ass man" so.. With that prep into how we kinda are usually.. Here's my problem- I have been up since 630 taking out oldest to college prep seminar all first half of day, then we had plans to meet with friends to take our other kids to fall festival, I also had a swing I found on Craigslist I wanted to buy so my schedule was jammed from the sec I woke. I called him after seminar and he didn't answer so I text him saying- " well I guess I will go by grab the swing, feed Michael, then head home so I can freshen up and we will head out" his response was "ok, I'm getting Serenity chicken nuggets now" sooo I do what I said and go home. I walk in give a kiss and automatically I get massive attitude because I didn't bring him food and he's starving?!?? I felt bad but I assumed he was eating when he got her food- but mainly, I've been running  around like a crazy VERY pregnant and swollen person, and ur gonna give me hell since I didn't pick u up fast food when u were just at a drive in? And you've been sitting here waiting for 2 hours for me to come home and u couldn't eat..? Needless to say our weekend totally went to shit he didn't go to the festival with us & my kids were dissapointed and now he went out for the night with friends to bars when I've been looking forward to his day off all week to spend time with him! I'm soooo upset because I don't feel his reaction is right at ALL.. And he says HE has every  right to be upset cuz I was just being inconsiderate and selfish. Now I'm in tears because I don't do anything all week and just really look forward to our time together.. HONESTLY- who's the bad guy here. If it's me- say so.. But I need to know if my hormones or common sense are at play here..
