From the perspective of someone who has loved INFJ's, this is because INFJ's are typically so caring, so loving, so accepting and so devoted that you start to forget that this is contingent on how well you treat them and appreciate them. They will love you completely, only if you love them in return. So if you are selfish and fail to appreciate their love, you will start to imagine that is something you will always have. Then you may begin to take it for granted. At which point, you divide yourself from them. I imagine this also happens with ISFJ's. INFJ's are lovely. Appreciate them and respect their ways.
I believe one can extrapolate this out to include many relationships between men and women.
It is so frustrating, how comfortable and dare I say complacent men become after you have been with them for a while.
If a woman is in love, guess what, she will be caring, loving, accepting, and devoted. I think we are better able to sustain love and appreciation for our partners, *while in their presence*!
I have been in several critical relationships where the men I was with were taking me for granted despite my confronting them that by the time they realized their mistake, it would be too late, and I would be gone, but for some reason they would not listen, and surprise, surprise after I left, they came to their senses and realized I was the girl who got away.
Not to derail this thread, but this is something I cannot stand.
It does me no good, provides me no warmth, when I hear an ex say that I was the love of his life, what would have helped and worked was if he realized this *while* we were going out.
I will love and care for you, I will respect and admire you, trust you and devote myself to you if you love me, appreciate me, and cherish me back.
Simple as that.
I can't speak for all women, but I can speak for myself and at least a few others by stating that being appreciated and cherished by the one you love feels, feels.. hmm, feels better than any ordinary word can attempt to convey/express.
