Its possible that my friend likes me?

This guy is a friend of mine for a few months. Since I met him, he has a girlfriend, but I noticed that sometimes he looks at me in a "special way", lets say it... Well, last week he said to me that his tattoo on arm - I never saw it, because the t-shirt covers it - is a picture of his ex-girlfriend. He said that kidding of course, but I think that he waited for some kind of reaction coming from me, because a few days later, he mentioned something about his girlfriend and then looked at me, but again I didn't reacted. LOL
Its possible that he might like me? What do you guys think?
Thanks

It is possible that he likes you, of course. It is also possible that he doesn't. We cannot know, you would need to ask him. Are you interested in him? If so, are you interested enough to risk potentially getting in the way of his relationship? And enough to be the rebound, if he were to break up?

He just wants attention. Hes not asking you on a date and talking about his girlfriend is not moving conversation anywhere. Hes not focused on you.

Speak to him directly. It helps solve open issues

I'm a guy - I also think you should be direct. But here's my analysis:

Is his ex-girlfriend good looking? If so, he might be trying to show off what he's worth. That's a good sign he's interested.

If he's talking about his ex-girlfriend's hobbies or opinions, then he's not interested in you at all.

The guy has a girlfriend. Until he's single don't even think about whether he fancies you or not. And stop trying to read something into every little thing he does. It it irrelevent because HE HAS A GIRLFRIEND.

He wants the attention...I would say stay away from him. If he can't respect his current gf, there's no way he will respect any other woman.
