Hi Miss Laura, I am sorry you are disappointed,

I think you'd feel much better about life and relationships if you'd get involved in other interests . You can derive some self-esteem from your involvement in other activities.
You will likely make some friends and won't be so laone and so let down when some stranger does not show up. When you feel better about yourself, you won't need to get a boost in your self-esteem from people you do not know. You will feel so much better about yourself, you will learn to set more boundaries with strangers and with anyone who is not good for you!

I hope you will find something healthy to do with your time, since the gentleman is not showing up.

Concerned about you!
