Could my former friend's girlfriend be jealous?

I had been friends with a guy for a few years and once he started dating his current girlfriend he cut all his friends from his life, most of whom call him and receive no response, the few who do say he isn't the same jovial person. A while back I decided to do a cleaning spree on my FB friends list and low and behold he's gone. I thought it was weird and couldn't find him by looking up his name, soon enough I asked a mutual friend and she said no he still has his page. A month later I see one of his kids (who happens to be my younger brother's friends) and it seems his troubles and possibly my being blocked on his dad's FB precipitated by giving a birthday gift to his sister. I never dated my friend and I'm close to two of his kids. Later on as is my usual custom, I tried to send him a happy birthday text (iPhone messenger) it's going through the whole sending process for most of the day and finally towards nighttime changes from blue to green. I'm kind of daunted for a moment, but realized 1 she has issues and 2 she doesn't trust him. I'm one of those friends who is happy for my friends finding good people, yet I find certain relationships toxic. My friend was the joyful, open, confident, and kind type; yet he has disappeared and been replaced by a quiet, brooding person.
I've been in toxic relationships before and I keep thinking he's in one, but at the same time I keep hoping he's not. I just remember my own experiences about being cutoff from friends until my breakups.

What's wrong with my laptop?

My compaq laptop fan is making a loud whirling sound. It's the only laptop I can get iTunes on I'm having an awful time getting on the other one which is also a compaq. I tried to get on iTunes the other night to get all my music back on my iPod it started making a loud whirling noise with the fan. It made me nervous because it's never done that I just shut it off I didn't want to be on it long. What's wrong with it? How can I fix this?

How to get 64 bit on Windows 7 ?

I got a compaq laptop I'm trying to get iTunes on it but it says I have to download 64 bit. My other one is a compaq we didn't have to download anything to get iTunes on it. But the other one is having problems with the fan it's making loud whistling noise which scares me a little. It's a lot older than this one. How can I get 64 bit on the Windows 7 compaq laptop?

Help this is a very important question! Why does my friend Sadorian have Q-tips in her lunch bag?

Is this completely normal? I was isolated at birth from socialization so I'm completely confused. We're in the class of PLTW and she pulled out her iPhone XI out of her lunchbag (?) and then I peeked in there and she has Q-tips?

Is this normal?
