I have a situation I need advice

So basically during the summer I was asked twice for my number from two different guys from my neighborhood . they didn't know each other. one of them named donell .. I had the most intrest in and the other one was just for fun but I cared for both of them . Today I went out with my friends and it was a bunch of guys out side ( including donell and brandon ) so I walked straight pass both and brandon said " yo that's wifey right there " and the donell looked really sad I felt so bad ... how should I explain this to him ?
