He makes me so angry

My boyfriend is so childish he's always playing and joking around I'm all for joking and being goofy but I can't even talk to him about my morning sickness or stomach aches without him laughing and joking around I don't even see how someone can find things like that funny...it makes me feel as if I should just keep everything in my pregnancy to myself I know I'm very sensitive right now I just feel alone 🤦🏼
