You didn't choose her
over yourself, you chose her
for yourself.
You decided that a life with her was worth more to you than an attempt to make competitive fishing a paying proposition in the immediate future. And she probably wasn't trying to make you choose between her and fishing- she probably felt that a straight job right now would probably benefit the family more.
From a hypermiling perspective, it's time for the pulse. Pulse hard to get to your glide.
