You want to change who he is with magick? Doesn't that sound a bit selfish?
If he wants to play video games and do Facebook all the time, that's what he wants. If he wanted to pay attention to you, he would. Don't try to change who he is with magick. That's very manipulative.
If it bothers you, talk to him about it. If he ignores you and you don't like it, FIND SOMEONE ELSE!!! If you love him, but you want to change him...it is NOT HIM that you love. If you REALLY love him, you'd just enjoy the times he does spend with you and allow him to be his own person. Otherwise you're just trying to make him into someone else.
There's an easier way to get someone else. Just find someone else.
Trust me, even if someone gives you a spell to do this...you won't like the result. I'm not preaching here, I'm talking from personal experience. When I was younger and more foolish I tried something exactly like what you are asking for. I've also seen others try to do this. It is not a good idea.
When you try to change someone with magick, you're forcing your own will over theirs. That interferes with their free will. It's like drugging someone, or putting them in a cage. Eventually they will lash out at the control. Eventually it will break down and you will be worse off than you were before.
Again, this is from experience... this is not just words. I've seen it many times.
Why don't you look for a spell to make yourself happier with who you are? Or maybe a glamour to be more attractive, if it's sexual attention you're wanting. Those only affect YOU and therefore will not interfere with his free will.
Or you could do what I do and just find your own thing to do until he wants to spend time with you. Why make your happiness dependent on another person? You should be able to be happy whether or not he pays attention to you. If you are not, then you should look into why you can't be happy on your own. The problem is probably not with him. It's probably something you are unhappy with about yourself.
Don't try to change someone else to make YOU happy. Change yourself. Make your own happiness.
