Search Results: show how much i appreciate him

I have this friend, we use to be kind of best friends. A guy Im so comfortable around I can walk around him with no make up on or hangover asf. He stayed around mine couple of times aswell. We can not talk for months and then when we do, it's not awkward and we have so much fun. I know him for like 2 years by now. My sister introduced me to him.
He was going out with my sister and he was in love with her. He did everything for her but she didn't appreciate it and was so cold to him& played with his feelings.
Now he likes me a lot. He lives miles away from me but is coming to see me no matter what. Skipping his work, college just to see me, it costs a lot aswell to come to my area. He is telling me that he loves me, changing his profile pic to a pic with me, his wallpaper is with me aswell. I do believe that he actually loves me. Too long to explain, but he does a lot for me and shows lot of effort.
But I don't love him.
I don't know how I feel about him. When I'm with him I do wanna kiss him but then I regret it. We only made out, we never slept together but if we would I wouldn't mind. Even though he slept with my older sister like 2 years ago. I just don't want anyone to know coz it's kinda strange. If he wouldn't love me and would be only after sex then I'm alright, I would join him and be friends with benefits. Just don't wanna hurt him. He has been hurt so many times in his live. He doesn't really have family and it's hard for him.
I don't mind kissing him or sleeping with him, just don't want a relationship. And he knows that.
His 18th bday is coming and I dunno what should I get him. He didn't get me anything but he made my bday the best. Everyone left me so he organised a party for me. So it's not like he didn't get me anything, he got everything for me. All the alcohol and other stuff. He just made the day. Bless him.
I'm not sure if I should get him anything. Maybe just a bottle of champagne and a card? Or something more? Or nothing? I dunno
