Im six wks pregnant and I cry, I scream, I'm angry and I'm all over the place.... I have constant mood swings. I told my bf to please be patient and understand that my outbursts are irrational so as long as hes patient and remains calm I won't errupt. I also apologize when I know i'm not being myself. He should understand.
Two options, you can sit down with you SO and explain that he is not to take you seriously unless you are still angry about it hours later, or when you feel your temper start to rise, remove yourself from the situation. Go for a walk, take a cold.drink, have a shower, something to take.your mind off the thing that's frustrating you. I went with the first option. I told hubby that I know I'm going crazy, but I really can't stop it and I feel a lot better after getting it out. So now he knows that he shouldn't take to heart things that I say in anger, because I just say them to get them out of my head (that conversation works better if you're both in a good mood and can joke about it)
