missing jerry

it's been weeks since my son had left our house.... he wanted to spend his summer vacation with my in-laws... now, he seems to be enjoying his stay there, he doesn't want to come back to our house... whenever i would ask him when he'll be coming back, he'd just let out a grunt and mumble something undecipherable over the phone...
i miss my son so much. we used to stay up late and do our own thing together.... he'd be playing with his toys while i'd be doing some reading or take-home work beside him....
now, it makes me think that probably i did a poor job of being a mother to him...i wasn't good enough for him to miss me or want to be with me.... i thought i was doing an ok job of being a mom... what with all the things that i had to do all at the same time, juggling my carreer, my other side businesses and taking care of their daily needs single-handedly, it thought that my performance level, if not great was at least, good enough...
i dont even know how to act on this emotion that i'm feeling right now... it's as if i've been rejected by my own son...
