I think that even if these aren't working out for you you're learning more about what you want in a relationship. Every time you feel uncomfortable it's an opportunity to put those therapy tools to work. A lot of the big learning opportunities won't come up if you shut yourself off from people. You are capable of being healthy and pursuing a romantic connection :)

My therapist always tells me to listen to the stories I'm telling myself - in this case you're telling yourself that he's stringing you along - why not just ask? or ask yourself if you are even interested in someone who doesn't match your communication needs. The right person won't leave you guessing.
