It is the threshold at which you realize that you are immersed in the other person and that your time with them will be a fairy tale rather than a waste. I love you.
There is no such threshold. Sometimes the relationship is removed in a day or two, and it is removed before, even after 6-7 months of hanging out. It is a clue about the quality of relationship which is low.
Human is selfish, what you call love is a complete illusion. It is simply a more acceptable and unique more human-specific pattern of the desire to mate in the human genes. That is why even when you think you die of your love, these feelings end after 1-2 years at the most. The best thing is to manage not to be attached to the opposite sex in any way. It is being completely free in this life that you come once without drowning in any unnecessary responsibility.
We haven't gone from that threshold for 9 years. We said so much. We're still there, you can't say come in, you can't say pattern, you can't say the same again. It's easy to say the back is so blurry
