Maybe she wanted to ask if you sent the masks and money yet?
This is why trying to mind read is never good for you. Just as one thing jumps into your head, you progressively let it escalate till anger/resentment take over.
I know its hard, but you really need to stop trying to ask the why's and the when's.
You really need to focus on just slowing things down a bit, for your sanity, for your health, for your situation. Its like if think by pushing her out of your life, your just suddenly going to forget about her. Sorry my friend it doesn't work that way.
The more you push the more you feel guilty.
Tonight, I want you to take a job around the block, if SHE comes into your mind, SPRINT till you burn the stress off. If its too late or too cold outside. Drop on the floor and do pushups till you cant do another one. Burn some frustrations off.
Allow yourself to grieve, but don't wallow in it. If you really want her to regret it. Then make yourself the best damn MAN out there!!! Who knows what the future will bring, if you allow yourself to give her time and space, not resentment and anger, you might just surprise yourself and her.
Keep a log on running, same route, time it, write it down. Keep a log of how many pushups/situps you do everyday. Try to surpass/beat ea day. Get to work friend, you can do this. It starts with taking care of you!!!
