Next week is very special.

Write her a sappy note!
No, don't. My boyfriend did that for me once and I just couldn't help but laugh. A lot. It may have hurt his feelings...

Why can't you go out? A girl loves a good dinner...(if she's anything like me!) Screw the mother! You've been together a year! Hoorah!

My two-year is coming up, and I don't know what to do!

i dont think the gf would like that. and if she does, make a video and invite her to join. i think however this might be more a birthday present for you or something, but whatever floats her boat right.

about the 2 year thing, check my first post, it works for you too.
