Hi Priscilla, What a great topic for conversation! Haha, I love it.
As someone living in Spain who travels a lot, I can tell you that the dating scene here varies significantly depending on the location—people in the South tend to be more "affectionate," while those in the North can be a bit more distant. They definitely have their own "unwritten rules." Here is my experience regarding your questions:
1. Is it easy to meet other single people? In general, yes. Spain has an extremely social culture. Unlike other countries where life happens behind closed doors, here life is out on the streets, terraces, and plazas. This makes eye contact and spontaneous interactions much easier. At the end of the day, there are also many people in the same situation as you.
2. How do you meet people here?
Apps: Tinder and Bumble are the most used. Bumble is very popular among expats because it tends to attract people with a more international profile.
Meetup Groups and Events: This is probably the best way. There are tons of "Language Exchange" groups, hiking groups, and so on—there is a huge culture for this in Alicante, for example. They are perfect because there’s no pressure; you go to practice Spanish or English and end up meeting people from all over the world.
Real Life: Don't underestimate the power of "friends of friends." In Spain, if you’re invited to a dinner or a tardeo (going out for drinks in the afternoon), it’s normal for the group to be open, and you'll likely meet someone new there.
3. Safety when dating Spain is, generally speaking, very safe. As with anywhere, it’s best to meet in public places for the first few dates. However, the "going out late" culture means there are always people on the street and plenty of light, which provides an extra sense of security even at night.
4. Cultural differences and etiquette
Physical contact: Don't be startled if there’s a lot of physical contact (touching your arm, standing close while talking) or if the first date ends with two kisses on the cheeks. It’s part of the local warmth; it doesn't necessarily mean they are looking for something serious immediately.
The bill: The most common thing is to split the bill (pagar a medias). It’s a deeply rooted sign of equality, though sometimes someone might offer to buy the first round.
Punctuality: Relax when it comes to the clock. This is Spain! People usually arrive 10 or 15 minutes late, which for many is considered "on time."
Direct conversations: Spaniards are very direct and passionate when they speak. What might look like an intense argument is usually just a lively chat about football, politics, or food.
5. The dilemma of "leaving Spain" This is the big challenge of being an expat. My advice is total honesty from the start. Many expats are in the same boat as you, which creates a mutual understanding. If you're looking for something serious but with an "expiration date," there are people who prefer to live intensely in the present. And if something very strong develops, many couples end up becoming nomads together!
But hey, I’ve seen a bit of everything 
I hope this helps you navigate the waters of love in Spain, haha. Best of luck!
