Is this a sign of having trust issue?

[Lam N.]

My husband and I started our REI business together. We've been doing better than I had imagined. Along the way, we've had other investors with money coming out of their ears willing to partner up with us. Sure, it was always very tempting, considering we've never had that much cash to begin with. But we always said no. Even now it's just him and me. To be honest, we cannot even imagine ever letting anyone else in. I know that we could make a lot more money by letting other people in. But it just doesn't feel right.

You think it's a trust issue we're having?
