I thank you for your post, and I definitely appreciate what you're saying, but it's only been two months. If Eric is your girlfriend, you are still quite in the "honeymoon phase", if you will, and you're already talking like you are in a long term relationship (I know you say you've known him for years, but working in a business really brings out a different side of people).
When I finally found a co-founder through my friends group, I was really excited. I thought everything would be peaches and gold, and for awhile, it was. But as time went on, I realized I was the only one working on the project, and that he wasn't doing anything. After 8 months of waiting for him to do actual work, I decided to move on without him. Now I'm not sure what do and I've probably delayed my start-up because of it. I'm not trying to dissuade you, and I really hope you've found you're match, but don't say "Mission Accomplished" just yet :)
