How Do I Apologize...

I broke up with my boyfriend because I found a couple of fake nails in his car and he said he didn't know where it came from. I broke up with him and told him to leave. I kicked him out. My daughter came over from her father's house and she was wearing the same kind of nails. I asked if she had those in my boyfriends car. He drove her to her dads for me because I was cramping and she said she dropped the box in the car and she thought she picked them all up. Now I have to figure out how to apologize after the way I acted and how I kicked him out
