IIf he makes a plan, he sticks to it; or if he has to cancel, he reschedules in an appropriate way.
A guy who’s interested in getting to know people you spend time with is interested in forging a long-term relationship with you.
If he wants to show you off and wants you to get to know people he spends time with, he's really into you.
This is not to be confused with a “not-date.” A date can be defined as an activity he’s asked you to do with him that’s not at your place or his.
He asks you questions about your life. He wants to know how your day was, what’s new, how your sister is, etc. He’s genuinely interested in getting to know you.
If he doesn't save his weekends for his friends, you've got a boyfriend material on you hands.
If he asks you out in advance, and he puts thought into the future, Kudos to this guy; you deserve it.
