Man, I just bought a copy of Full House for my wife yesterday. It's an all right show to me, not one of my immense faves, but I don't feel lame buying it. I bought it for her because I love her. There's a lot of shit in my massive collection that, if I were single, I would never ever own. But it goes back to calling it "my massive collection". It's really "our massive collection": mine, hers, and our son's. Noone's gonna say anything anyway, but even if they do just shrug and say "she bought it" and don't elaborate. It's no big deal, guy.
There have been posts like this all the time in the HTF's film section; I think this is a first for the relatively new TV section!
Go back an re-read what you wrote: "
We get a kick out of watching it..." Maybe her "real" gift to you is to try to find a way for you and her to do more things together and for her to get that same special feeling of closeness she gets from you during these times you watch it together. For my wife and I, it's ER. Watching ER on DVD together is very special somehow. We discovered this during the S1 release, and it strengthened during S2's release. When I posted S3 news recently, she and I looked into each other's eyes so deeply and with such warmth because we were glad to know that these nights were coming up again. What nights? Well, whenever she would get home from work (her work shift ends a couple of hours later than mine, near or at the time our son goes to bed), we would try to squeeze in an ep of ER as much as we could before our own bedtime. We'd make popcorn, snuggle up on the couch, really get into it. For some reason it's an event for us. We feel close.
Your GF's real gift this Valentine's Day is this "lame" signal that she wants to feel closer to you. Depending on how you feel about her in return, you should decide how to respond. Think about it. Good luck!
