What does he really mean by “i want our friendship to grow”?

I’m in a complicated situationship. We started off as friends when we met at work. It’s been 10months and things are more than just a friendship. We’ve been there for each other through rough moments, when I was laid off and he lent me money to help me from loosing my truck. To me helping ease his anxiety after he was falsely accused of something at his new company. To sharing laughs, to watching our favorite tv show together. Then something changed. We started kissing each other, holding hands in public, and having cuddle sessions where we meet during lunchtime and cuddle while eating lunch and talking about our day. I tried suggesting dating early on in our friendship, but he got all weird about it. I never brought it up again, but now there’s physical affection and we tell each other “I love you”. There was a time where I’m not quite sure how it happened, but we had phone sex, never actual sex though. Today he gifted me the most beautiful plant with heart shaped leaves, he said “I want this to be a symbol of our friendship. I want our friendship to keep growing.” He’s gifted me lots of things, but recently this and his favorite sweater have been the most sentimental gifts he’s given me.

I’m scared to ask him of more since early on he said no to the idea of “dating”, but it feels like we’re more than friends at this point. What does he mean by “I want our friendship to keep growing?” Is he giving hope at an actual relationship?
