Why shouldn't I check if he has a girlfriend ? Why speculate when you can get information ? And well, a girlfriend would be a major issue !!! So I'd better check now.
If you can stop thinking of a man and just drop things, well then you are not in love. Reminds me of "Hitch" : " I have waited my whole life to be that miserable ! And if that's what it takes to be happy, so be it". Sounds very wise to me.

I don't have the feeling to be waisting my time. What fun things could I have done???? So being interested in somebody is a waste of time ? How so ? I don't get it. It is the most valuable and fascinating thing there is.
