Buying you flowers, paying for your dinner, making uninterrupted eye contact with you during said dinner — these are all classic signs that someone is into you. These signs are so "run of the mill" that they're impossible to mistake. But relationships aren't always that black and white, and figuring out a potential partner's true feelings about you isn't always so simple. Aside from the obvious signs of affection, there are a few unexpected signs someone likes you more than you think.
Since every relationship is as different as the people in them, it's impossible to generalize the exact signs to know whether or not your partner is "that into you." The way you new potential partner acts around you may be completely different than the behavior of an ex in the beginning of your relationship, which can cause you to question whether or not they really like you at all. But believe it or not, the nuanced, subtle signs that you might not expect are oftentimes even more powerful indicators of someone's true feelings than the grand gestures or stereotypical come ons.
Instead of calling it quits because your new SO isn't giving you the cues you expected, take a step back and evaluate their behavior through some of these more unexpected but important signs that they do indeed like you.
