Did my guy friend mean it when he texted “love you” after a favor?

So guy friend of mine whom I've known for 3 years now (we have been pretty close, texting, talking, he was there for me when ex&I broke up, he wiped my tears from my cheek, etc) has asked me for a favor every now and then and he sent a text saying "love you" after I did him the favor, however this is the first time he's ever said that, but I didn't get the context behind it, thought he was not being serious so I just did a laugh emoji and told him your welcome. He calls me "sunshine" "beautiful" "my dear". I did not bring up the "love you" text as I don't want to overthink it or anything, but I'm not sure if he actually meant it or if it was meant in a friendly manner like when you do something for a friend and they say "love you"(he also asked if we could be friends with benefits prior to this, but we have not slept together yet or anything) Thoughts? Opinions? I'm a little inexperienced with this type stuff.
