I think it's a fun idea to get something for the FI. Since I was so excited about my diamond, I wanted to get him a gift too So, I got him a Wii! He's been wanting one but didn't get it b/c he was spending money on the ring, the puppy, wedding, etc. I put it in a big box, so when he came home it was the first thing he saw. I think anything thoughtful would mean a lot!
