My ex reported sexual assault tot he police, and I'm expecting a call from them. I'm going to ignore it.
Why  would you ignore a call like that?
I just really don't like my ex.
Bad breakups a rough to go through, but if your ex needs help on a situation like this, you should provide it. The person that did this to her could do it to someone else if you don't help.
I'm going to ignore it. It's not my problem.
I understand that your ex is no longer involved with you, but sometimes there are certain situations where bygones must be bygones. Their life might be at stake, how would you think they would feel if they had no help at all? How about just helping them this one time, and then fully moving on?
