Marry her! Just kick the other dude to the curb; unless he's the technical guy and you're the biz-dev guy, then you'll want to carry on the affair behind his back at least until other developers have been hired and your code is well documented.
If you or her are the technical side of things, then just quietly disable his access to the organizations Github and repositories. You might want to reincorporate as well, leaving him off the new papers. "An oversight!" you'll say. Then you promise to get it fixed "As soon as you aren't so busy." Change the company's name while you're at it. Or just recreate the entire business under a new entity.
As far as the girl is concerned, let her be the one to break the news after she's cleared out the apartment, you've moved into different offices (or workspaces) and all email accounts/phones/etc have been locked down with new passwords. Or, just don't break the news at all. Your choice. Same outcome. Bewildered vs. Angry. No sweat off your back.
Just pretend the other guy never existed and don't return any calls or acknowledge him every having been someone you've known.
..a few years later
He shows up at your offices just after you've IPO'd and you've become a paper billionaire. He's got the Winklevoss Twins with him and he smacks you in the face just before serving you with papers.
..a few years after that..
You're the CEO of the largest social network on the planet and people across the world turn to you and shower you with accolades. The old boyfriend was just a several hundred million dollar blip on the screen. The girl, still with the company but not with you, has since moved on to a younger model and you've gone bald and your neckbeard is streaked with grey. You spend a lot of time on 4chan. More than you used to. You'll think wearing hoodies maintains your coolness and connection with the team.
OR..
You could just put the feelings aside and run your company. If the girl wants to end it with homeboy, then leave that between the two of them. Your involvement in things need not be disclosed. Likely he'll quit in disgust or depression or he's actually happy about it because he's been looking for a girl that isn't quite so easily going to jump ship for his cofounder. If they actually break up, and if he quits, then you can get things going with your little superstar. If they break up and he's a pro and doesn't quit, then you'll have to ask yourself, is she worth it? If she is, then ditch the company, marry the girl and then figure something else out. Many people might disagree, but true love is worth more than a dozen successful startups. I married my cofounder and I'd give up the business in a second if I were in a position where I had to choose. But, you gotta know it in your heart. I've been with my wife 4 years now and it still feels like the first day.
Good luck. Oh and post pics (of the girl..) We need to see what this startup-wrecker looks like!
