Incidences of this are quite rare. The only ones that I can think of at the moment are in The Lyonesse Trilogy by Jack Vance and Thumbalina by Hans Christian Anderson.
Usually 'friendships' between fairies and humans have a certain 'stand-offish' quality to them as would be expected of distant species. Even relationships with elves have something of this transitory quality to them. Unions with mermaids also appear strained and often end unhappily. The most successful inter-species relations with humans that I know of are with Nymphs and even here there are numerous incidences of unhappy endings.
fairys were once real but not any more and yes they do fall in love with humans very often.
With fairies they love it when humans behave well. I don't they'd be attracted to us unless we have done things that are good to make fairies trust us. Fairies can be attracted to good humans but it is pretty rare.
fairies love us! if you believe in them they will believe in you and care
she made them fall in love
No. Fairies do not exist and it is impossible to become a fairy.
The reason fairies are scared of humans is because in the old days people tortured the fairies. There are many reasons for fairies to be afraid of humans. Sometimes the fairies are much smaller than humans. Humans don't often understand fairies very well and hurt them without meaning to. Most of the time though fairies are afraid of humans at all, because fairies have magic and humans don't. Fairies have always known how to take care of themselves. Sometimes it's the humans who should be afraid of the fairies.
Its a natural thing.

All humans can fall in love and almost all of them do at least once in their life.
