Bottom line..expect commitment behavior when one has not been clearly established. Entering each relationship thinking it will lead to marriage Each relationship has a reason, season and a lesson attached to it.
Instead of wondering what he does with his days and nights or who he is talking to or texting, I suggest that you focus on getting to know who is in front of you.
Until the two of you have come to a consensus that you want to commit to an exclusive relationship, do not expect a commitment or commitment behavior. Don't assume that it is a committed relationship when all the signs point to a hook-up or friends with benefits relationship.
You are NOT in a committed relationship until a clear statement of commitment has been expressed and the terms have been mutually agreed upon.
During this early relationship phase, most guys are just smelling the flowers and trying to decide which one to pick or IF he wants to pick one.
Just because he has shown interest in you does not mean that he has forgotten about all the other women in his life.
