Do you think it's wrong that I told my employer I lost someone to avoid telling them it was my abortion?
Why didn't you want to tell your employer? Are you still working there?
I wanted to keep things to myself
You should have been more honest with your employer and tell them the truth. Your employer trusts you to be honest with them and it is unacceptable to lie. You could lose your job if you are being dishonest with your boss.
I really can't tell them it was a abortion, I was sexually assaulted and thinking about it makes me feel sad.
That can be a very tough thing to go through and it's okay to be upset about that.
