Okay someone plsss help me out

I’ve been talking to this guy for almost 6 months now. We are both very interested in each other but we haven’t hung out in so long becuz of me. For some reason I’m so nervous to hang out with him since we started expressing feelings toward each other. He’s getting irritated because I keep putting it off and saying I’m busy or I can’t. I don’t know how to fix this but I’m starting to lose him because of my issues and I don’t want to :/

Also my sister/ parents can’t know I’m hanging out with him.
