She did not post the flowers I gave her

Problem/Goal:

I could not help but feel sad that my girlfriend did not post any appreciation post for our valentine's date and the flowers I gave her.

Context:

We celebrated Valentine's day yesterday and I had everything prepared for our date. Weeks before Valentine's day, I already had everything planned out. I really wanted it to be the best it could be. To complete the experience, I also secured a bouquet of roses that I'd give to her on our date.

Hours before our dinner date, I had struggles with the delivery of the bouquet. Apparently, it was really difficult to book a rider in Dangwa that would deliver to my office. Thankfully, after waiting for hours, the bouquet was delivered, though super late. Since the flowers arrived late, I had to rush from office to my house to get ready for our dinner date.

When I got ready, I then picked her up at her place, and we arrived right on time for our reservation. I then gave her the flowers, and she thanked me for it. She also told me that it was beautiful. I then shared the struggles I encountered to secure the flowers, and told here that I'm glad she liked it. Our date night went well, and I can say that we both had a great time.

After our date, we then parted ways. As I was about to sleep, I noticed that many of my friends' girlfriends or wives posted the flowers they received and thanking them for it. Some with sweet long messages appreciating their boyfriends/husbands. I then remembered that one of my workmates who received her flowers even asked some of us if we could help her just so she can properly take a photo of her bouquet and thank her boyfriend through an instagram post.

I could not help but feel sad that my girlfriend did not do the same for me. No sweet posting on social media at all. I know this sounds silly but I felt like she did not truly appreciate my efforts. I know she's not really the type of person who posts on social media, but I was hoping this time would be an exception knowing that it's valentine's day and that I had to went through a lot just to give her flowers. I even had to ask her if she could post our picture last night because it has always been me who posts our dates etc. and she would simply repost. Although she did post our photo, I felt like she would not have done it if I did not ask her to do so. It was also just a photo of us, without anything.

I guess my question is, was the sadness I felt valid? Or was I just OA? I have not told her about this yet because I feel that it's kind of petty. Also, is there any advice you can if your partner is not as expressive as you on social media? How do you do it? I really want to know how how because we also had this issue before. I know that I need to do adjustments on my part as well so I am open to your suggestions. Thank you everyone!
