What does a guy mean when they say "youre perfect for me, im just not ready to be ina relationship"?

ive been dating this guy for 2 months now and lately hes been very attentive to me always txting and calling saying i miss you and calling me his love lots of sweet talkin . also saying he feels closer to me lately and stuff and one night on the way home from a bar with his friends he said "lets reevaluate things, i want to take us to the next level" so i confronted him on his txt and behavior lately and he says "I think ur a great girl ur perfect for me but im just not ready to be in a relationship right now".... will he ever be or am i being strung along and nothing is ever going to come out of this?
