Hey man, Two things: 1) Congrats! and 2) DO NOT GIVE UP!
I am "in the same position"...wife is due in 5 weeks with our first child, but I've got 2 bikes in the garage, and another one due to be picked up this weekend. It /is/ doable. No, my bikes don't have huge budgets (my current project will have <$1500 when all said and done) and I shop carefully and slowly. The build is taking longer because of that, but I also have the luxury of having multiple machines, even while starting a family.
You own the bike, and I'm guessing you have all or most of the expensive bits....re-evaluate your build and see what you need now to ride this next spring, and what you can do next winter. It's not like you're making payments on a new machine that's just sitting there un-usable.
One valuable lesson I've learned is to splurge on the wife a little bit here and there... I surprised her with some stuff for the baby, so last week when I said "hey I'm gonna buy a bike from a local club member", her response was "OK cool do you need me to get the cash from the bank for you?"
FWIW, I'm not "loaded"....I do OK, but if my paycheck disappeared, I'd be on the streets in <2 months. I /have/ learned to prioritize the hobby(s) though and it's surprising what you can do with limited funds for the motorcycle.
I repeat DO NOT GIVE UP! 8) I have seen a lot of generosity among the people on this forum...if there is something that is just unobtainable...reach out. Everyone would prefer to see you have a semi-finished rideable bike than have to give up your hobby...even for a reason as good as yours.
