When I'm with a girl, should I always be with her?

It's fun spending time with your gf or bf, but too much time together could actually be too much, so if she says she needs space don't make a big deal out of it, you just need time to miss each other too, and she needs her gurls just like u need ur guy time too, and just live life like she's a good friend :) that's what i'm doing with my bf and our relationship of 5 months is actually great so far :) and we haven't gotten in one fight...yet. lol.
