Am I (24 f) committed to my bf (male 23) and is this just a passing crush?

TL;DR If I look at pictures of another guy's face in his stories late at night, ghost him when he asks me for advice about another girl because I was really upset, pretend to like the same things that he does, try to stare at pictures on his phone when he is showing them to someone else.

Even when i stop looking at his stories to prevent myself from getting emotionally invested, I still look at a picture of a text that he sent to another girl when it's 11 pm my time am I that committed to my boyfriend even though I'm planning on staying in my relationship? Also I haven't seen this other guy I mentioned for two and a half years. The other guy is confused by what's going on because he thinks we're good friends and I haven't responded to him even after looking at the text.
