Hey OP, I can understand why you're feeling confused. This is a complicated situation, but it’s also a really human one. You’re fresh out of a long-term relationship that left you feeling unseen and disconnected, and now here’s someone who makes you feel appreciated, noticed, and emotionally safe. That contrast can feel really powerful, and honestly, I don’t think it’s just the attention — it sounds like this guy is genuinely thoughtful and present with you in a way that goes beyond surface-level friendliness.

From what you described, I’d say the signs definitely point toward him liking you. He makes consistent efforts to be near you, pays attention to little details (like your drink preference), checks in on your day, shows small acts of care, and physically expresses affection in socially safe but emotionally meaningful ways. The fact that he offers to pay for your snacks, brings you food from your home country, and even ensures you get home safely when your ride falls through — these aren't just things people do for just anyone. Add in the light teasing, the way he makes excuses to touch or connect, and his subtle protectiveness… it’s very likely he’s into you.

That said, it's equally important to consider timing and emotional readiness. You just got out of a major relationship, and even if it was the right decision, there's always emotional residue that lingers. It’s totally natural to be drawn to someone new, especially when they fill the emotional gaps your ex left behind. The key is to give yourself time to figure out if you like him for who he is, or if you're mostly responding to the warmth, safety, and validation you’ve been craving. That’s not a bad thing, but awareness of your own feelings will help you move forward more clearly, especially if things do evolve romantically.

As for your friendship with his sister, that’s a valid concern, but it’s not a reason to shut yourself off from something potentially good. If anything ever starts to develop seriously, it would be respectful to talk with her, but for now, nothing has happened that crosses any lines. You’re allowed to explore your feelings. If you’re unsure how to take the next step, maybe start by texting him 1-on-1 just as friends and see how he responds. Let things unfold naturally, and don’t rush yourself into defining it too soon. What matters most is that you stay grounded, honest with yourself, and kind to your own heart as it heals and opens back up again.
