P/S - I love you

Met someone who is different from the people I've known all these years. He do not mind me telling him about my past experience and that I'm older than him. Though it's still hard for me to think about going out with him, it's fun when I chatted with him. He worries about me when I had a mood swing and was quiet the whole time. He did not pry too much, instead he told me that he's willing to hear me out whenever I wanna tell him. And everyday or everynight, he will never miss out his goodnight kiss and at the end of the chat would be "P/S-I love you." He tells me about whatever happens to him everyday, like getting his driving license banned for an invalid and unreasonable reason, his friend's birthday party, his studies. He always tries his best to spend more time with me, eventhough it's impossible to do it face-to-face.
