Yes, he can’t stop worshipping one of the one good things that’s always been a constant in his life. He doesn’t fear much, but losing you is one of his worst fears. You’re part of him. You remind him there’s good, there’s pure trust, whole hearted and unconditional love. So he makes sure not to take advantage of or twist that.
He lays his shit all out with you. No talk around, no tricks. He can be less than with you if he’s having a hard time. Touching you makes him know you’re real, he’s real. He’s capable of cherishing and protecting.
You are another purpose for him.
