If someone ONLY compliments on your appearance?

Hi guys,

when a girl receives lots of compliments ONLY abozt her physical appearance from a. guy she's dating and the guy previously told her "I'd like you to be my girl and I really like you. I'm attracted to you." , and this guy is trying to support/help her when she needs help for example with accomodation or so, how serious is he then?
The conversations weren't just superficial all the time but also personal..
Does he really likes her for who she is and wants a serious relationship or is he just hoping for sex?!
