@Savvy1419,
Good morning!
There are tons of confusing snippets of information out there. People do, mostly, behave similarly when it comes to showing attraction (as a lot of that is a cross between cultural norms and cues, and evolution, e. g. people smile because we know, culturally, it works. We wash because that works out in an evolutionary sense, as people who wash tend to live longer because they get fewer diseases and they tend to mate more because they smell better), but there are always outliers.
Therefore, as opposed to kind of generic questions such as, "does he look in your eyes a lot?" I'd rather you asked yourself questions more like this -
- Do you spend a lot of time together?
- Are you treated with courtesy, decency and respect?
- Are there impediments, e. g. there's already a girlfriend in the picture?
- Does this person seem proud of being with you, sharing their time with you and others because they think you're great, or are they hiding their time with you from others?
Or you can take the bull by the horns, and ask. E. g.
Steve*, we've been friends for a long time, and I really love spending time with you. And now I'm getting a vibe that you like me. Do you? Because I definitely like you that way.
And see what happens.
*If his name is Bill, don't call him Steve.
