Is it normal to think i still love my ex?

So about a couple months ago my ex boyfriend had broken up with me because of my friends and others not approving of us dating. He left me in a terrible heartbreak and I believe I'm still heartbroken now. Recently he has been staring and playing around with me and asking for hugs but he does that with everyone he's cool with. It got me thinking though; would I possibly still like him? When he did that stuff with me and asked for hugs and everything, I started to get butterflies and get nervous and just started thinking that I loved him once and I could possibly still love him. Maybe that's why I haven't been in a relationship with anyone since, because I might still love this guy. What do you guys think? Is it still normal for me to have feelings for him even though he might not have them back for me? And if we did like each other back, risk my friends and professional relationships just for him?
