Tough one. I think since you are so anxious about the response (the "return to sender" thing) that it's too soon.
All the cards and gifts and such on Thanksgiving and Christmas were a lot of pressure, and it really hasn't been all that long since your last text contact. I think your anniversary is coming up soon too right? I'd maybe wait until after that (if you're emotionally ready at that point) - so that you're past all the "usual" card occasions and it won't be tied to any of those. Remember how we were talking about her both expecting and dreading a V-day one? I think there's a good chance she might also feel that way about your anniversary.
Just my thoughts.. will be curious to see what others think, as well.
