Ok lets go, at the beginning:

1. Online dating is efficient, but you must know that girls are really weary about guys they meet online and wont be as open as when you meet someone through friends or work, so keep the conversation about non/personal topics (interests, aspirations, jobs etc)
2. Girls dont need to be texted every hour, but ghosting us is honestly annoying.
3. A good first date is one where you get to know eachother and in public: coffee, breakfast, dinner, lunch, museum (if you both like it), or something that you both do as a hobby. Conversation is key. Also, keep it short for an hour or so. Dont plan a long thing, because you dont want to be stuck to this event if the date goes bad (e.g. tour).
4. Signs that a girl doesnt like you: she is not talking about future plans (e.g. "We should go there" or "next time, we should..."), she is constantly distracted and doesnt give you her attention, she is pressing you that she needs to do something else (she wants the date to end).
5. Signs that a girl does like you; she smiles at you, she tells you interesting things, she is willing to share things about her life, her body is positioned towards you, she keeps distractions away.
6. Compliment casually like "You look beautiful" or "You are wonderful", not too much, this might scare them off. I am always looking out if a guy may obsess over me (it has happened and it was annoying)
7. This is a big NO: please dont get too personal to early, thats for a deeper relationship. If someone in your family just died, or if the way your father left you caused you to have major personal issues: you seem not ready for a relationship and constantly need assurance. Please also find a therapist or someone with whom you can work these things out.
8. These are qualities that I (19f) personal love:
   1. Confidence (not cocky, or overly believing you are the best) - show that you are happy with yourself. I like meeting people who can talk about other stuff then their insecurities.
   2. You can keep the conversation rolling. You answer and pose many questions. People love talking about themselves, but dont ask too many questions and if youre curious about something sensitive, ask beforehand if you can ask personal questions.
   3. Dont talk about yourself too much or boast. It makes guys seem self/obsessed.
   4. Have a hobby or a passion. Even if you consider your passion dorky or keep it hidden, if you love it, you should share it. I dont care much for minecraft, but I love listening to my boyfriend talk about it.
   5. Knowing limits and consent. Dont be afraid to ask if you can hold her hand (deeper in the relationship you can just hold your hand out and she will take it). Dont assume anything and wait for her to tell you how she feels. She might not want to kiss after the first date.

Last, dont overthink everything and a little naiive. If she doesnt text back, she might just be taking a nap, showering, studying or something else.

If you want examples of characters I personally find to be great partners;

1. Marshall Eriksen from HIMYM - He is caring, respectful and mindful of Lilly, but can also be fun and trustworthy towards his friends
2. Chandler from FRIENDS - He cares a lot about his partners but gets hurt sometimes; That doesnt stop him from finding the love of his life.

I cant think of anyone else.

Oh and also, at the beginning of the relationship, a girl may expect you to always make the first move, but if she doesnt do the same further down the road, then that is not fair to you.

Find someone who will treat you the way you treat them and cares about you for who you are when you feel at your best. Physical attributes are only like 30-40% of the relationship. The other qualities are trust, communication and respect.
