In our culture we have a concept to indicate a moment when a man or a woman has a special feeling regarding their partner. I have seen this reaction in many countries when for example a woman draws a man’s attention when the man is walking with his wife or girlfriend and vice versa and that man’s partner becomes very annoyed and even I have seen that such things in many cultures can cause many deep problems in families. All people like to have a partner who belongs only to them and cannot accept that their partner have a relation with others too at the same time with being with them. As far as I know, the only infinitive which can convey the matter in my question is “to become possessive of somebody”; but what do you name such a sensation? “fanaticism” or “passion” or “zeal” or…? For example do you say: “His husband is very passionate and has a lot of passion over his wife” or something? I wonder if you help me to find my needed word family; I have searched a lot but I have found nothing.
