My Girlfriend asked for space, even just for 5 days only, though she told me she loves me that much.. She asked for space because we've been arguing or fighting the past days & that's too much for her to handle. I can't think & absorb anything at this point, what do you think should I do?

Give her space for 5 days, what's the problem?

You will loose her if you don't give her what she is asking for.

There should not be a time limit on the space she needs... it will take as long as it takes.

The fighting and arguing has gotten too much for her to handle,if you love her give her the space she is asking for and more time if necessary.

You need to loose the... pressure.
