Donor Stress

I'm on CD3... and I'm thinking about trying this cycle. I just don't know what to do about our donor issue.
BIL is no longer our donor although we have an option for another KD who wishes to remain anonymous "always & forever" so I can't really say much about him. I'm not so happy about that because if this person is in our life our kid may figure out who he is and that will be an awful situation... this person may not be so bright but that's possibly giving away a lot.
I'd go back to the sperm bank and the clinic but D is being pretty stubborn about the money.
I'm stuck in the middle.
I can't believe we're on try #7.
