8. He lets you have a key to his place/He asks to move in together.

It’s no longer a question of just spending casual time with one another anymore. He wants to really share his life with you. He wants you to feel welcome into his world because he’s really serious about wanting a shared future with you at his side.
9. He moves his schedule around just to accommodate you.

Time is the single most valuable thing we have in our lives as human beings. And if he’s willing to share a substantial bulk of his time with you, then you know that he isn’t just playing around with you. He’s the real deal and he isn’t afraid of prioritizing you above other things.
10. He tells you that he loves you.

And at the end of the day, you can believe him or you won’t; but if a guy tells you that he loves you, and you know that he’s serious about it, that’s all you really need. And it shouldn’t be enough that he tells you about his feelings. He should be able to back them up with real actions and gestures as well. One way to gauge his sincerity is by noticing the subtle signs he enjoys your company. Pay attention to how he engages with you during conversations or how he makes an effort to spend time together. These actions often speak louder than words, reinforcing his feelings in a genuine manner.
