I love the idea of using a crappy situation as a source of inspiration for self improvement. But prioritizing speech therapy to cater to judgmental ass holes who make fun of others for being different? Nope! If anything, it sounds like your stutter saved you from dating a stuck up snob. If you're a candidate for speech therapy and benefit from it, awesome. But the motivation should come from within, not from people bullying you to change things about yourself.
