Oh, dear. I am sorry you are going through this. I want to promise you that you won't be single forever. Some people find their mate when they are very young, others when they are a bit older. It happens at different times for different people - I have friends of all ages (20s to 60s) who are happily single and fulfilled, and friends of all ages who are happily married. It just happens when it happens.

As one of those who still hasn't found the person to marry (I am 41) I can speak from experience when I tell you that it can be frustrating, lonely and exasperating. I have learned a few things along the way, however:
1) If a man is not willing to meet in person with a couple of weeks of chatting, then he might not be that serious about finding a relationship
2) If a man isn't willing to meet half way, he may not want to do the work or exert the energy it takes to be in a relationship
3) Surely there are some good single guys closer to you than 7.5 hours of driving - what types of activities do you enjoy? Have you thought about taking a community education class (golf, tennis, pottery, language)? It might be good to just broaden your horizons a bit and get to know some people outside of your regular circle.
4) I guess it is better to have only had to do that drive ONE time rather than do it a bunch of times and then find out he wasn't into a relationship

Sometimes we just have to let go knowing that much of what happens with other people will never be understood by us .... they are only going to say what they want to and even if it doesn't make sense, they may not ever give us the closure we need. We have to find that closure within ourselves. Letting go and moving on is hard, but it is so very necessary.
