Why would a guy from work still look at me after choosing to sleep with someone else?

26 yo- not much dating experience

In the first week at my new job there was an outing with all departments. I was in a group with people in their 20s and we played truth or dare. A guy asked me who is the cutest and I said it was this guy. I felt embarassed. He seemd to feel the same. Another round. They dared me to kiss him and I did, on the cheek. After that we would smile at each other when we would meet in the hallway and I would catch him stare at me from time to time. He seemed nervous and sometimes he would blush.
A new girl joined our team. Very straightforward she said she likes him, followed him on instagram (I don't have social media). On the other hand I kept it a secret. The girls from my department wanted to help her.
A company party was approaching and he started to stare at me even more but he would look away when I looked back.
At the party the girls were pushing the new girl onto him while dancing and she would lean on him while talking. It made me uncomfortable so I left the group to dance. Not long after he came and put his arm on my lower back. I put my hand on his arm but I didn't push it away. The music stopped, we were both nervous and he removed his arm. The other appeared and put themselves between us and that girl gave him her drink to taste it. At some point he got separated again from them and touched my lower back while passing by.

I had to leave at 2 am with 2 other girls. He didn't see me.

From what I found out they continued to push her onto him and he ended up driving her home. A few days later they slept together.

I felt horrible.

They are some kinds of friends with benefits because she still thinks about her ex.

The attraction between us remained the same but he started smiling and staring at me as much as he did before sleeping with her recently (6 months later).

What should I even think about this?

Why are putting SO much emphasis on him...(checks notes) staring at you? It doesn't mean he likes you, it means he is checking you out. He is likely attracted. But attraction is not interest. It sounds like that other girls went after him and outworked you. You can't sit around and do nothing and expect a guy to gravitate towards you... smh.

Attraction would be like liking someone's appearance/finding someone appealing.
And interest would mean wanting to also approach them/try something with them. Right?
He did both of them.

You're right about the second part. I might've been too passive but only sex it's not something that I want.

[spartan55]

Who says he only wanted sex?

[Asker]

No one. It's only my perspective on things. I'm the type to get stuck on people for years so when I saw he moved on to the next one so fast I came to the conclusion that he wanted sex.
Or from his perspective I didn't show enough interest and I left (who knows where) -> this girl showed interest so why not?

[spartan55]

Yep. For you to conclude he only wanted sex because he 'moved on so fast' is based entirely on your emotions, not facts. (moved on from what by the way?)
Often girls complain about guys only wanting sex when they don't even bother to find out.
All guys want sex. Some guys want the relationship that goes along with it.

[Asker]

Thanks! I'll keep that in mind.

[Asker]

I think there's nothing I can do now. friends with benefits or not they are in a relationship.

Honestly, he's still looking at you because you still physically exist.

I wouldn't get too focused on things like that. You'll drive yourself crazy.

No doubt he wants to sleep with you too

[Asker]

I thought so.

Men look at everyone. Ignore it.
