Is Aries man Trying To Make Me Jealous?

I don't really like him THAT much but whenever he's talking to another girl he always looks my direction and purposefully talks to everyone in the room but me. He says hi to my sis and my mom but never me. I haven't doe anything to make him angry so idk any other reason he'd have ro do that besides making me jealous. I actually like his best friend who is a Gemini!! I'm a libra btw...
