This is an interesting question,and there's no correct answer.I never had a girlfriend,but I think real love is that people in love are willing to do things for each other,and I think lovers should put themselves into other people's shoes and really think about others,and I guess people in real love are blind,they cannot figure out the truth...hehe,may i just have seen too many soap opera..:P

When you are in love with someone, you want to spend every possible moment with him/her.

Not really tangible, it floats somewhere in the void! So it depends whether you consider entities invisible to the naked eye real or not. Add to this that the elements in it are combined in a strange way that you would not normally expect as real , like in a dream.
