How do you know he cares?

He says "we" instead of "I"
He wants to talk to you
He is able to make you laugh
He doesn't laugh at you, He laughs with you
He comforts you when you sad
He remembers things about you without you telling him
If you cry, he offers a shoulder without being sexual
He talks about the future of both of you together
He wants to meet you
He introduces you to his mum
He wants to meet your family
He compliments you on your look
His friends know who you are

Off course, the list continues...
