Men will always be boys. Inside their grown manly bodies hide little boys who like to play all day and don’t want to take a bath. Not literally, of course. But the point is, you can never act like a guy’s mommy. Start taking care of him, and he will appreciate your material instincts, but also will associate you with someone who loves him unconditionally no matter how bad he is - his mother. Once that happens, he won’t stay with you. But he’ll keep coming back only when he needs comfort.
