Great news about your father! Love his attitude, you have to live in the moment. The rest can wait.
Very romantic, yet simple Valentine's Day. It's the best way. You don't need to let the special day rob you off your money, yet it's nice to do something as a couple. I mean, you paid €3 for that t-shirt, so that's €3 less for a fancy meal if you ate somewhere else (plus more). Not worth it, what's worth it is good old memories and that t-shirt. ;)
