Shanita......
Okay, I am trying to be friends with one of my exes. Why? Because it benefits me to do so. Its a purely psychological response. I really have to feel like the last 5 years have not been a waste of time. I feel like if I threw him away, I am throwing away five years of my life. I am seeing him through fresh eyes, I am no longer bitter and more importantly, instead of feeling like I lost someone special, I feel like I dodged a bullet. He's an okay guy, but it was really just another shitty relationship, and he was just another shitty boyfriend. Now that we both recognize that I was able to move on and look for my perfect match. While I haven't found that person, I'm having fun looking. As for him, hey he's just someone I know. I don't love him, I don't desire him, but he's someone to call when I need a ride to the airport or to drop off my car at the mechanic. Purely utilitarian.

For me, I think this subject can be easier for men than for women. Generally for men, sex is like peeing in the bushes and for women lots deeper. That's why they have a harder time being friends more that men can. I love almost everybody...... almost. Shanita, you speak of them being functionally pragmatic. Interesting. More useful than not, but still a friend. And who couldn't stand to realize another friend. Unless it is for all the wrong reasons.
Ultimately, you are the one that needs to be happy. Be totally selfish here if this is not you first time around the block. You deserve it.... there's that word.... hummmmm. Don't worry, be happy. Live in the here and now moment is some of these relationships. What do you have to lose? All about me? Time for you to shine....
