what IS the right thing to do?

Why am I always doing things and then regretting it after? Why can't I just think rationally with my head instead of my heart? That is really something I need to change.

There was nothing wrong but I had to find something to pick on and now look at what has happened..
Things must be really stressful for him to have flared up like that... Didnt I promise to be understanding? Instead of being understanding, I found things to pick on..

All I can say is sorry....
