Am I wrong for feeling upset?

So for Valentine's day I knew we wouldn't have much money. I just had our son last month on the 18th of January. So all we did for Valentine's day was watch TV and order pizza. I got him his favorite candy and juice (I also baked him a cake) since I couldn't get him something expensive. It's the thought that counts right? I was also given tickets to a car show I wanted to go to but he didn't so we never went. Now I'm not complaining that I got nothing, I expected it. After all, all he bought me for Christmas was a $5 pair of pajama pants meanwhile I spent about $100+ on him. Again, not complaining about what I got. But yesterday morning I woke up to a ton of flowers in my apartment. I KNEW they had to be someone else's, why? I never get flowers unless I guilt trip him. Last time I got a half dead single rose from him. I got no flowers for mother's day (I had to guilt trip him to get me ANYTHING because I originally got nothing and he said not a damn word to me), our wedding anniversary, my birthday, when either of our kids were born, literally I have to BEG to get flowers. I expect nothing from him partly because I know he'll forget or it just won't happen. So I asked him who all the flowers were for. They were his mom's. My heart sunk a little but I already knew they weren't mine. I just wish he'd show some attention sometimes. Because I feel I'm slowly sinking and he's just watching. It may just be ppd kicking in as I have a 1 month old and last time I got it was around this time. Or the fact that I lost my grandpa to cancer last week. Am I wrong for getting upset? Am I overreacting? Cause I feel like I am😔
