Friendly gesture or the beginning of something more?

I have a guy friend whom I do happen to like. I'm always careful to try and not assume if he likes me despite the constant flirting and teasing he does. We don't talk all the time and don't see eachother often but when we do, he can't help but smile from ear to ear and tease me.

Recently, he reached out asking if we could meet for lunch for my birthday. He's a bit cautious and frugal so I didn't think twice with thinking that we were meeting their and paying for our own meals. To my surprise, he wanted my sandwich order from my favorite place as he wanted to pick it up and told me to go to this one particular park as we were going to have a picnic. When we met, he had a little bag packed and surprised me with my favorite beverage and favorite treats and set it all up nicely next to me. He seemed quite proud of himself as my reaction was absolutely was full of delight. He's usually a very serious and proper guy with everyone but with me he's rather silly. He kicked his shoes off and plopped down and was lying down sprawled out next to me but not too close. We enjoyed all my favorite things and then we both had to go to work. No kiss, no hug, just always this awkward "see ya later" between us.

I can't think of one guy friend that would do this just as friends. In fact, I'm not so sure he'd even do this for anyone. Perhaps my friends are different but would you do that for a girl that was a friend or only for someone you had feelings for? Am I wrong to think he was actually trying to be romantic or slowly set the stage of what's to come?

To give further context, we've friends for over 5 years. 3 years ago, his long term relationship ended in shambles and m it was extremely difficult for him to trust much less commit to anything or anyone. I'd ask him out all the time and it was always an excuse. He always said he was non committed to even making plans no matter how simple and platonic they were. So, yes it's a bit surprising that all of a sudden this nice gesture happened. I am still unsure of how he feels given how guarded heis
