Realistically, how much attention does a girlfriend need?

I ask this out of curiousity because I have never really been in a relationship. But my question is how much attention does the average female expect to receive from her partner on a daily basis? Especially when you do not believe in living together? I ask because while I really want a girlfriend, I am also really introverted and seeing people everyday honestly drains me. Spending time even with my friends and presumably a girlfriend expends me, it takes a lot out of me. I have to prepare days in advance and then recoup for another couple days before I can do it again. Do girls expect for you to visit them every single day and/or call and text them constantly? Because if this is the case, then I'm not sure if I'm ready for a relationship yet. I would honestly have no problem seeing my girlfriend only on weekends or calling her only every couple days or so. Yet it seems like the girlfriends of all my friends expect for them to drop everything--even work and school--to spend time with them on a daily basis at all hours. I just cannot do this. My introversion and social anxiety would go through the roof. She would make me suicidal or depressed. Are there girls who do not mind having a more distant and/or independent relationship with less contact all of the time?
