I feel really snappy at my boyfriend right now and I don't know if this is normal or not??
Is it because of the stress from your new job?
No, I've decided not to take it.
Sometimes things going on in our lives can make us feel stressed but you shouldn't take it out on your boyfriend. It will make your relationship worse and maybe cause it to end.
Maybe you are right but I need to express my feelings.
I think that it is good that you want to express your feelings, there is just a nicer way to do this. You should not get snappy with your partner for no reason.
