First of all like others said, there is no problem with not having a girlfriend. But also, it sounds like you're self-sabotaging yourself by pushing away female friends and hating yourself for the way you sound. I know (from personal experience) the stutter can be debilitating, but I and many other people have found love in their lives, there's no reason you can't. I hope you can forgive yourself the bad reaction, especially if you haven't had much experience approaching women. It takes time to figure it out. But the stutter doesn't have to be the thing to hold you back.
