He never likes my pictures

So before my bf and I got together he was obviously talking to other girls from tinder. There is this specific girl that he follows on Instagram that he literally liked every single one of her pictures before we got together.

We got into a relationship and I realized he never likes any of my posts. Never liked any of my pictures. I posted a video of him on my story with background music and it was really cute and he said nothing about it. He watched it and never said anything about it.

Idk am I weird for feeling this way? I feel like he thought that other girl was better looking than me or something.
