He Doesn’t Include You In His Future Plans
Do you ever listen to him when he talks about the future? Does he ever say “us” and “we” when mentioning said plans? If not, then he not interested in committing to you because he’s already thinking about a future without you in it.
Things like vacations, new jobs and moving to a new home are just a handful of the future plans that a man would think to include his girlfriend in before making a big life decision. Since he doesn’t think of you that way, he is making plans for his future with absolutely no thought of we.
