I’ve always said that, in the early stages, the dating process is a research project NOT a relationship. You need to pay attention (with all 5 senses) to determine whether a man’s really “feeling” you or just hanging for the heck of it. This article offers a few key “signals” to help you assess his romantic interest in you.
Caution: These are signals that MAY mean he’s serious about you; but they are not, alone, guaranteed proof. To know for a fact, you’ll need to ask, NOT just hope or assume.
