Wii - I think one thing you should learn out of this, is that you've got enough on your plate, so you need a partner who is stable enough in their own life that it doesn't add stress to yours.
I know I've dated some men who were having chaos in their lives, and EVEN THOUGH neither of them ASKED me for help, I still worried about their situations and needed up getting stressed out about it. So I've realized I need to find a guy who doesn't add to my already-high stress burden.
Doesn't mean partners don't help each other out - but I need a guy who carries his own weight, and knows how to live a life that isn't crisis-to-crisis.
