where it said "power f" it was supposed to say "power feeling or ego stroke"
In other words, you are not married to this guy, and you like the -- what, power f? of having him around you and interested, but in fact you feel kind of stuck with him? And you don't know how to be merely a co-parent with him if you were to drop the illusion that this is a love match on your part?
If I have paraphrased what you're saying correctly, it sounds like the only way you can find your way through this maze is to remember that he deserves, (as do you), someone who is crazy in love with him. It takes a lot to make a lifetime commitment work, and the first thing that it takes is someone who is ready to sacrifice all to be with him, as he is to be with her. If you like him OK, but really don't want to be that person, let go so he can find someone who feels that way about him.
You just dont want relations with him but you love his company sit down and you tell him
