Hi strawbz11,
First off take a few big breaths and know you're in good hands coming here. You ex is trying to paint a picture of you being the bad guy. That's what alcoholics do to get others on their side. You are not the bad guy. You most likely were the person who tried to help. Know that you didn't cause this. You have sent this stuff back and that is all you need to do. Now you need to focus on you.
You will get through this. Their are lots of people here to help you. Lean on then for advice. Keep being be strong.
