<human>: I met a boy in high school and we dated for over 4 years. We broke up early last year when I was 21. I started seeing people in the fall and realized that I really didn't know how to "date" as a big kid whose dating pool extends beyond the grade school classroom. 

I've casually dated a couple of people and it all goes the same way: things start out great, then they start to back off, and eventually I send the last message that never gets replied to and we never speak again. 

I don't go deep into personal issues, I don't whine about exes or talk about my plans for the future or marriage, I don't send four texts in a row asking where the person is or who they are with. I make it a point to ask more questions about them than talk about myself and like to think that I'm a fairly good conversationalist. 

But obviously I'm not perfect, no one is, and I'm trying to figure out if these are just cases of incompatibility or if I'm breaking some sort of dating etiquette rule that I missed out on being in a monogamous relationship for so long. 

The only thing I can think of that might be it is that I had been inviting the guys out to a lot of events. But this isn't necessarily coming from an "I need to see you four times a week so I'm going to invite you out to stuff all the time" type of thing, it's more of an "I like your face and am going to this thing if you want to come, but if you don't I'm going to go by myself or take a friend" type of thing. 

Is there a rule about invitations or something that I don't know about? Or is this just how dating goes some times? I'm not looking for *the one*, but I'll tell you it's definitely a hit to the self-esteem when this happens over and over. 

Someone, please, write a book on dating rules in this twenty-first century, tinderized world. I'm a lost foreigner who doesn't speak the language.

Summarize the given text in a few sentences.
<bot>: I don't know if I'm breaking dating rules or not but I keep ending up getting hurt and ghosted and I want to figure out what I'm doing wrong.
