Can I have some help please?

Tyisha • 20years Old
I really like a guy I've been speaking to but I've never been the kind of girl to be able to speak about my feelings or open up to people... Can I have suggestions on how to tell him I have feelings for him please he's said he has feelings for me but I just can't speak about feelings but now I am realising that I have to as I don't want to waste a chance with him. 
Can anyone help me with something to say to him please? And how I can show that I like him and only him?
Thank you xxxx
