Except yours isn't really like op's at all. You did an activity with your SO and you paid attention to each other. Op was ignored and left to just watch him while he played.

But it wasn't Valentine's Day specific. We do this every weekend :P Actually as I write this we're getting ready to do the same thing again lol

If it were any other weekend OP's man would still be kind of a dick, but his dickishness is increased because of the expectations placed on the partner during such a "holiday". My point is that it doesn't matter what a couple does or when they do it. If a person is going to treat you like this every weekend it's not fair to expect that to change just because of some retail holiday. She doesn't deserve to be ignored, I'm sure, but would it really be such a big deal any other weekend?

This is just how I see it, don't have the facts but just to explain: it kinda seems to me she's just gotten used to being ignored. Especially with how she found it hard to be mad at him or how proud he was to just take a few moment to give her chocolates. Which means, yes it's sad, but I can understand why she was so sad when a holiday that's supposed to be about love only gets her that. And then to the fact he asked if she had anything planned for the /weekend/. It sounds like he'd planned something special. So while many seem like they don't celebrate it, he'd made it seem like they would.

As I've said: He's kind of a dick. But it's made worse only by the fact that it was on Valentine's Day weekend and there were expectations that he apparently didn't meet. My husband and I got into an argument and we didn't give each other presents. Yes we spent time together, but it wasn't as if he lavished me with romance. I could be mad, but I'm not (because A: We don't have any money to throw around, and B: We were long distance for three years, it's enough for me just to spend time with him). Only within the boundaries of one's expectations can things like this be considered an FML.
