Hi there Mark, Welcome to PTalk.com 
Sorry to hear about your relationship, if it starts over, its good to understand that things will definitely not be the same as before, there will always be that particular incident which will flash your ideas back.
Congrats on your weight loss , it is not easy to loose 25lbs just like that, I know because I lost weight myself as well.

Ammo is a great choice for your first purchase, it is an all rounder product.
For opening the door, you might want to consider some IO which is tuned for icebreaking.
All the best Mark.
Cheers!
