Is he just not that into me if he isn't pursuing me strongly after 5 dates or is it normal to wait hours/days for him text and ask me out each time?
Maybe I'm old school, but I don't get why a person who is into you would make texting his choice method of communication. I like to actually talk to my partner.
Maybe you should pick up the phone, arrange a date, and actually talk to him and ask him why it takes “so long” for him to text you/ask you out.
Maybe he's just dealing with his everyday life. On the other hand, he might have three other girlfriends. Maybe for him, this is the strongest he's ever pursued someone and he's scared he might smother you. Maybe he's working by some other set of rules.
If you want a relationship, you'll have to learn to communicate. Maybe this is a good place to start practicing that.
Is it a bad sign if a guy doesn't text in the day, takes 1-2 hrs to text back and when he does text, it's after 9 pm to ask me out for a future date?
I think it's a good sign. It might mean he actually has a job that is important to him, or studies, or some other semblance of a life, and that he only bothers with text messages at set times of his day, actually leaving him to be present to the people in front of him when he is with them, including you, when he goes on a date with you instead of trying to have a relationship by text.
