Activate one of the profiles. Even if you're not quite ready for a relationship you will meet some nice people and hopefully make some new friends along the way. As long as you don't expect the right woman to come along straight away, I think it would be a good thing to give a go. It will help build your confidence too and allow you to flex some of those charm qualities that come out in your post when you're not talking about your sitch - funny, encouraging and self confident. You got this.
