people dont always fall in love fast, it is different for everyone, but certain things factor in to falling in love, ones past relationships effect current ones, say if soemone was hurt in the past they may be less likely to let emotions show in the next relationship,
It is not that they love the ones that really hurt them but they dosent want to loose them because they like them and in this regard they does not recognise that they are being hurt. during this period it is not possible for them to think that they are disregarding the loved ones.
they need the love Answer I don't think we intend to hurt the ones we love. We are human and make mistakes and sometimes the ones we love may get hurt by those mistakes. If they didn't love us they wouldn't get hurt because our actions would not effect them emotionally.
Yes you can substitute on the fly. Usually midfielders who play on both sides of the ball (offense and defense) are the ones that change frequently on the fly. But sometimes when the ball is on the defensive end for example, a coach may want to substitute an attackman.
