You deserve a kick-ass relationship. You deserve honesty, monogamy, and awesome sex. Make sure you're not settling for Mr./Mrs. Meh. In the long run, only the magic will preserve your relationship, so you'd better get on with the task of finding THE ONE.
The goal is never to blame the other person for the breakup, even if they were the reason you are breaking up. Always take your responsibility for the miss. And make it about the chemistry, the mix, the overall relationship and not about them or their poor behavior. Remember, you are leaving the relationship, not trying to teach them a lesson or educate them.
I am not willing to spend all of my free weeknights going for coffee with women that are marginally compatible. But back in the summer of escape velocity, I tried and tried and tried. It was exhausting.
I believe in order to find our lover we need a fairly clear picture of what they might be. Way beyond looks, the construction or destruction happens over the course of the initial weeks of "dating." What forms beyond the initial chemistry is what will remain beyond the heat of the sexual newness.
