You should try another bf, if you love him you will be back to him, in the worse case you have a relationship with another for a while. To break the ice you could have a virtual relationship to see how is it the progress.
@sarah Don't want to make friends quickly, it takes time and confidence, as it can easily be destroyed at the first disappointment. Just be yourself and don't have high expectations. This will show you more confidence and security by talking to strangers. But always be cautious, after all there are bad people at every corner, but good friendships are forever; Just filter.
