Can't think of a really thoughtful gift more me and my girlfriends 5 year anniversary
get her a piece of jewelry that means something to the both of you. Think back to where you had your 1st date, and think of something that was there that the both of you either laughed at or whatever.
something thats really thoughtful. and take her out to the restaurant or place you went to on your 1st date. She will love that. It will show that you remember that far back and really put thought into the anniversary.
Or book you both into a relaxing weekend away? But I think the jewelry idea and the place you went to on your 1st date is a good idea.
You could get a joint pair necklaces that clicks or magnates together. That is kinda like saying we will stay together. There are a lot of very nice ones out there to.
What about a promise ring?
