Do guys use your name a lot when they like you?

I really like this guy and he treats me real sweet. Sometimes he treats me like one of the guys. Okay, well, sometimes I notice that when I compliment him or brag on him, he gets kind of bashful or giggly (well, I guess I shouldn't say giggly-but rather happier) and I've also noticed that when we talk on the phone, he uses my name a lot. For instance, I called to check on him b/c he has had bronchitis & when I was getting off the phone, I said "okay, well, I'll talk to you later" and he said "okay, thanks Julisa". And during the conversation, he said "well, Julisa, I have been real sick but, I'm getting better"...so there are tons of examples where he uses my name. One of my friends said these are sure signs that he likes me...what do you think???
