I don’t understand whether this guy likes, dislikes me or is indifferent?

We have a common friend and often see each other at his place at parties etc. He generally is nice to me, smiles, comes to me to talk to me and asks questions about me, gives me long gazes with smiles, once he even said in front of everyone that “he really loved me” because I always smile, etc. I like him and since I thought I was getting very positive signs, I asked him to go out for a drink just the two of us. He always said that he thought it was a cool idea, however every time I proposed him a day and time he said he was busy (it’s been a few months now…). I thought it meant he didn’t want to, but than when we see each other he goes like “shall we try to go for a drink the next week?”. But the next week, he doesn’t propose a date or if I do, he says he’s already busy…
