How to know if he likes me through text?

We've been talking for several months, and I don't really know if these are good or bad signs. He has only talked about girls once or twice, but that was months ago and he hasn't mentioned any exes or people he may like. We talk every day, but I almost always initiate conversation. He laughs at a lot of the stuff I say, and we tease each other a lot. He has a nickname for me that he knows annoys me. When he went on a vacation he said he'd miss talking to me (I said I would before). This isn't a really common thing anymore but he used to make fun of me by calling me stuff like "cutie" or "little cutie". Also he has seemed slightly protective before, not a lot though. However, he does make fun of me liking a guy if they like me, even if I don't. I hope I can at least get an answer explaining something, thanks for reading if you did. These are just some things he does, just little hints that could be a good or bad sign.

Also this would have been good to add beforehand... he's three years older than me (almost 4), so that could change up some opinions possibly.
