9. He had never shared his future plans with you

If he really wanted to play a special part in your life, he would eagerly discuss about the future with you. It doesn’t need to be too serious like having a family or something, but he would talk to you about his plans, perhaps his future European cruise, and you’d be in it. If he includes you in his future plans, it’s a big sign that yes, he is into you.

But if he doesn’t really talk about it at all, or if he did, but he never really had anything planned for the two of you in the future, then maybe it’s a sign that it’s not really you whom he would want to spend his life with in the long run.
