Should I leave my husband for a few days?

Easy…if your husband continue acting this way àfter you reassured him that you love him and that you will get thru it together and he keeps being a dick…then sweetheart,walk away. You are not his mother,you are his wife and he should stop acting like a insecure little boy.
He is a grown man,but seems really weak in his actions and emotions.
Tell him to grow some balls.
