Attraction to my boyfriends cousin?

To start things of: I have the best boyfriend. I love him and I would never never ever cheat on him. He is all I could ever wish for and more.

I actually never had this issue, because I find that every boy I ever talk to is nothing compared to my boyfriend.

I never found another boy more attractive than him. Ever.

But I met his cousin a while ago and we have seen each other at a few parties (my bf was there with me) and honestly we didn’t like each other that much at first.

We were always “roasting” each other and had quite the “sibling like” relationship.

Now we see each other frequently at school and get along better, while sometimes still “insulting “ each other jokingly.

He calls me devil because I used to have red hair and I always act annoyed when he comes to greet me and he acts fake hurt.

Now, he is complete the opposite of my bf. He isn’t very smart and is kind of a “player” but very easy going and chill, which makes him attractive. My bf on the other hand is very smart and can come off as stiff. I always found it cute and still do.

His cousin and I talked and texted a lot about his crushes and I helped him out even though he has a girl best friend who obviously knows him way better than I do. I always found that quite weird. He also is very physical, meaning he is touchy with everyone so I never thought anything about it.

He sometimes puts his arm around my shoulder and I kind of liked it.

But never mentioned anything to my bf.

A while ago he (bf) talked to me about it and said he would appreciate if I could become less close to him and of course I respected that.

So I became less bubbly but somehow that drove him (cousin) closer to me.

I really like his presence and sometimes get disappointed if he talks to other girls the way he does to me. ( being touchy etc.)

I honestly don’t know what to do. I am not that physical of a person, meaning I only like touch from a few people.

And that happens to be him.

I thought about kissing him once but it honestly stops from there.

I also haven’t thought about him that much until now.

I just don’t know what to do. I love my boyfriend and absolutely don’t want to break up with him over some silly little attraction.

I guess I want to ask if this is normal?

What should I do?
