dilemma

Right so a little dilemma I need help... so I've been speaking to this boy now for 3 months, we speak every day and get along great, we've met up and had sex a few times, but when we first started talking he said he never wanted a relationship, but 3 months on we are getting on well and I feel like I'm starting to get feelings for him, what do I do? I don't wanna ask him if he wants anything serious with me incase that scares him off? I need help....
