You know what. The one's that matter don't mind and the one's that mind don't matter. There will not be a more fulfilling relationship than finding someone who accepts you for you. Someone you feel so comfortable with you don't even think about your stutter at all. Been there. Also been in a relationship where I was mocked a lot. It was here that I realized something. Those who mock are insecure within themselves, they try to measure their worth against others constantly and when they find a person like you they pounce. This makes them feel better about their own shitty existence. It is them that are weak, not you.
