so i got a new job in retail and I'm not good at math. i can do simple things like count out change but my boyfriend thinks that if i hate math and I'm not that good i need help. he tried helping but i froze up got scared and stopped talking and i did that in high school too. he then started talking to my sister and she chewed him out for being to hard on me and it turned into a big deal. he said when he see's me again he's gonna break up with me. how do i get him to deal with my flaws and not get mad every time something happens cause i don't ever see his even though he has some obviously.
