Furthermore, what if the other person would be totally okay with that?
I run into folks who write me once, maybe twice before moving on their way for whatever reason. But, I would rather have people tell me "My ego was just shattered and talking to you for a few weeks makes me feel better." Or whatever the reasons may be. For me, I understand honesty and pride myself in tolerance. More to the point, I like to help people, what a better way than to help someone feel better about themselves!! Nothing would make me happier!
This requires boldness and a measure of vulnerability on your part though.
What this really solves is expectations of both parties. I have spent more attention on this as of late, it started as a means to protect my apparently fragile self esteem. I tell you what though, I feel more confident knowing exactly what I want, what's expected of me, and what the goal of my relationships may entail (how can I help you really? Which is of utmost importance to me)
Practice on me. Let's be confident together!
