I need my space, so for me, once a week is cool. I don't like talking to anyone 24/7...I need my alone time and it doesn't have anything to do with me not being into that person, but "too much of one thing isn't good." I'm not in a relationship at the moment, but I'll use my parents as an example. There isn't anyone in the world that I love more than them. I see them once a week and talk to my mom once a day. The rest of the time, I split between my friends, dating, work, and or just alone time to catch up on tv shows I like, reading, whatever it may be. It's different when you live with someone, but even then, people need personal space.
If you're the type that needs to see your s/o 3-4 times a week and she's not, then you guys maybe aren't the most compatible.
