Hi Questioning and FallenAngel,
Focus on being a better you, concentrate on being a better you. Your thoughts and actions are within your sphere of influence; what someone *else* does is beyond your sphere of influence. Thus if you obsess about someone else's actions (M, the love of your life, whoever), you'll find yourself with a helpless feeling (which can lead to frustration, depression, or any number of things). Let others be who they are, it's up to them what kind of a relationship (if any) they want to seek with you. Just be the best you that *you* can be.
I hope things are going better, sorry I've been logged off for a couple of days.
Love means never having to say, "Put down that meat cleaver!"
