It’s now been 3 years since Dayna died, Kyan needs to let go and move on with his life, both for his sake and that of his children, and if that happens to be with Perry then that’s fantastic, Kyan’s problem is that he doesn’t spend enough quality time with other adults, he needs to let Trudy and Jed help out with the kids as he could grow to resent the kids after a while, although I don’t think that is in his nature, he can be very immature at times, it’s a lot on anybody’s shoulders to have 4 kids under 10 years old and be able to cope with it all, particularly when finances are tight.
