When you can't have someone but you're not willing to accept that, you try harder and become more extreme about it. Either you win the person back or you drive him away.
It's very hard to gauge. Those are signs of intention. But they are not signs that this person is actually good in bed and is compatible with you.
You know, when you've been dumped, the one thing you love to do is just forget about this human being, and then go on with your life - but no, you just love them harder.
