It's normal. It's called getting over the honeymoon period. It goes into a period like this. It happens with every relationship you have. 3-4 weeks sounds about right. It's because you got so romantic and positive in the beginning that it doesn't last long. It looks like it ended for him but not for you.
After several partners, you'll still get it, but you keep it light and positive, so the honeymoon period stays longer.
You'll get used to it with experience... this period after the honey money period... the harder to try, the more it looks like there are problems... makes you "clingy" in away.
Be cool, you'll get over this naturally.
