i said its taken for granted if the people involved in a relationship are still together after all their fights and petty arguments and what not. we dont see it it but its there. chemistry does not have to be sweet little flirtatious activities or sweet talking or holding hands and so forth. you can have a slow chemical reaction too, something that's passive. And no relationship problems dot arise because of lack of chemistry. They arise when the fundamentals of relationship do not remain:- trust and respect. You can have a couple who are totally devoted to each other but they dont necessarily show the kind of "chemistry" you talk about. I would disagree with that ifc. But I agree with something though- what remians is love, trust and loyalty. That's all that matters, at least to me.
