Here is some perspective. I will be married 23 years in september. Not once: not one time, has my husband ever left a mark on me. Not once. he likes to drink, too.
Thats a long time.
Your boyfriend bruised your arm and you've been dating how long?
After six months of dating my ex boyfriend (the man I dated before my husband), he got mad that I didn't want to go visit his friends house with him. He threw me across the bathroom and I bruised up my body hitting the side of the bathtub.
Leave now.
