Many at times,ladies get caught up in a relationship with guys thinking that the guy they are sleeping with is in love with them when really,the guy has lust for her has no emotional ties to her,here are a few indicators that your "guy" is in lust with you and not in love with you.
1.Their is more fire than stability in your relationship,he will not be committed to you and 'a call away' type of person to you,he will probably see you once in a while when their is that intense quench in him that needs to be satisfied.
2.He pays more attention to your physical than your personality,he looks more on the outside than the inside,he is physically attracted to you.
3.Too much intimacy,less communication and time spent together,he would rather get under the sheets most of the times he is with you rather than talk and spend quality time with you.
Be warned,don't fall too hard for someone who is lusting over you.
