My ex boyfriend showed up at my front door last night… said he needed a place to crash because he was depressed and miserable. His mother passed away from cancer and he needed someone who he knew would support and care for him. I was scared but flattered at that. We haven’t had the greatest past… he was mean and hurtful and I left him. But now it seems like something might have changed. Was it a mistake for letting him in again? Is he going to go back to his old ways? I want to be there for this time in grief, I did love his mother. But maybe this is not the right thing. I am caught in the middle.
