Organize a professional photo shoot to obtain a portrait of the two of you as a couple. Frame the picture and put it somewhere prominent. Remember to make sure you give your partner plenty of notice so that she can get ready.

Contact your partner’s family and ask if there was anything she always wanted when she was a little girl.

For example if she always wanted a porcelain doll, buy one for her birthday.

She will not only appreciate the gift but also the fact that you were thoughtful enough to find out what she always wanted.

Use this idea if your partner is going to work and you are staying at home for some reason (Perhaps you are sick or are working from home).
Say goodbye to her at the front door and then immediately send an email to her work address. The email should simply say,
“Miss you already”.
The email will be in her in-box when she does her morning email check.
