Need advice

This guy I’ve had a crush on tells me he still really likes me and he misses me a few days ago. A few weeks ago we told each other we weren’t ready for a serious relationship, but we really care and love each other we wanna be friends. The day he told me he likes me he also tells me the adjustment was really hard for him, i confess it’s been really hard for me too. But he’s distant these past 2 weeks. He calls me during the day though still. His deal is he got out of a 3 year long relationship last March. I’m kinda emotionally immature i need to grow up but i like him a lot and i just wanna be closer to him. I promised him I’d try to communicate and be better. I want to make him a Valentine’s Day gift but I’m scared of rejection, is doing that too much?
