Is my friends with benefits giving mixed signals (21F and 23M) ?

We met about a month and a half ago and were dating him for about a month, then once he saw how serious I was about him for once, he told me he wanted me in his life as a friend, even though he really likes me. It was my idea to still have sex, as he said he didn't want me to get hurt. So we've been friends with benefits for a couple weeks now. However, his mixed signals make things feel like a relationship when its really not. Sometimes, we just hang out and cuddle and don't even have sex. He opens my car door for me, kisses me hello and goodbye, we go out places, he's been pushing me to spend time with his siblings saying they will love me and it will be a good opportunity to get to know them, orders us food and always offers to share, I watch him play video games, we are goofy together, he is constantly complimenting my personality and looks, always staring at me and laughing at my jokes, lots of comfort and physical affection, he texts every day and initiates plans almost every other day, he talks to his friends about me, called me his girl last night, almost said he didn't need anyone else but cut himself off, called me "his problem", etc. etc. This is all just very confusing for me. I feel like the main option in his life but still an option nonetheless.

When I act unavailable or already have plans, he starts to worry I am avoiding him or asks a lot of questions about my plans.
