I think it should be easy for you, but understand where your coming from. I saw your blog and you are super talented too!

Think of your coffee date, as just that! A coffee date, getting to me someone new who may have the same interests. Don't push the relationship, let it take its course, if it is even to have a course. Be polite and kind and courteous as you are in your posts...if you don't feel that same reciprocating feeling back then...Okay I only spent a hour with xyz and a coffee date. If it does go nicely, maybe another coffee date. Try to open yourself up to the possibilities of a good healthy relationship and what that might look like to you! No relationship is as rosy as it looks from the outside, even Mothers!
You must learn to love your talents, be proud and confident. What makes you feel loved, or confident in yourself....It appears you should have a good many things to talk about in this regard over coffee!
