I'm confused. Is this only friendship or something more?

He has a girlfriend. He has pursued a 'friendship' with me. It seems to be more to me. He gives me goofy smiles, always looks up when I walk in. He makes me coffee and brings me chocolate and always checks in when I have a bad day. He wants to hang out with me on weekends and even go on a trip together for 7 days. I said I don't think I can do it as I don't think it's right for the girlfriend and also I like him too much and it makes my heart sad. He said he's not that kind of guy and he hopes he didn't lead me on. I'm confused. Did he ever like me more than just friends or has he just backed up into the safety net of his relationship saying it was never like that. I feel like an idiot for doing the right thing. Did I do the right thing?
