<human>: Could you distill the essence of the text into 1-3 sentences?

I've dated two girls seriously so far. My first GF I dated for 5-6 years (when I was 18-24 yo, she was the same age), and recently I dated a girl two years younger than me for I'd say 5-6 months. Both broke up with me for the same reason: they wanted more "us" time and I failed to give them that. 

Personal background: I go to school, work a part time job (24-40 hours weekly), and I like to play video games and go out with other friends too. I am an introvert and I need to stay home every so often to recharge. 

What I gave: 

 * On average, I would spend 3/7 days of the week with my S/O. About 4 hours per date.   
 * Consistent daily texting, periodical breaks in-between texts.  
 * 30 minute phonecalls daily. 

What they want: 

 * Spend 5-7/7 days together. 
 * Both girls I dated had few hobbies outside of TV watching. I'm not judging, just saying that my presence was probably a big part of their life.

Sorry for making it so "mathematical" but really this is just what I'm comfortable with in a relationship. I know everyone is different and I should look for someone compatible with me, but I just need perspective. Do I need too much space? 

Are they justified in saying that if we were in a committed steady relationship, I should spend every free moment I have with them? It's driving me nuts to think that if I want to go steady with a girl, I have to quit my hobbies and give up my alone time to date them!
<bot>: My friends tell me my exes were "clingy" and not to worry. I am worried that I require "too much space". What do you think?
