Wow! Your co-founder is complete moron! They've been seeing each other for less than a month? And he wants to marry her and give her 10% of the company you've been spending 4 years to build, half of it coming from you? Do you realize the lack of judgment of that person? Do you realize that he's ready to screw you over for a girl he met 4 weeks ago. Do you really want to have him involved in high level decisions regarding your own future. The answer is obviously no to you giving away anything. If I were you, I'd keep my equity stake as it is and run and do something else! Life is short, and things can be rebuilt. These are MASSIVE red flags that scream that you shouldn't start a business with that person. This whole thing is going to blow up bad at some point, it's so painfully obvious. It might as well be now than in 2 years. Ugh, sorry about this. This is painful.
