I’m being very specific for a reason. I think I have a clue what family bond love is, but I don’t think I had experienced any type of romance in my 34 years of life.
I’m aware this answer will vary, but that’s why I’m expecting diverse answers and then I could make a sum of all of them.
At first, rapid heart rate, feeling unreasonably nervous to see them then overjoyed when you do. Happy to just gaze at them for hours or getting lost in their eyes.
Sometimes that dulls a bit with time (sometimes not) and is supplemented by feeling connected to them always and wanting to include them in your life. Wanting to do anything to make them smile and make them feel seen. And feeling seen yourself.
