Are you seriously looking to have soulmate or girlfriend?
Love takes time and effort and commitment and you just can't know that about someone else within one week. Not even one month. I agree about going through profiles, trying to know if they are real or not. It is tiring.
The same as I'm trying. I take time to make oneself known to someone one by one. I can't talks to everybody at the same time.
Follow your heart but use your brain to make good decisions.
