Your lovely lady can be counted on to celebrate all of your couple milestones if she really is in love with you. She won't even need to set the reminders in her phone. She will know exactly when your six-month or one-year anniversaries are coming up, as well as other cute little dates, such as when you first kissed or your first date. She can get totally sentimental when it comes to these celebrations because she loves you so much.
So, go with the flow, let her make a big deal about the day. But you need to put in a little effort, too. Take note of your anniversaries and set reminders in your phone so you can remember to buy her some flowers or get her a small gift. Celebrating helps you grow stronger as a couple.
