Controlling, insecure, or just in love???

What do you think about relationships when the couple can't seem to be apart for any reasonable length of time? Maybe they have to work together, or if they work separately one is always telephoning the other?

Are these people who are just very much in love? Or is one partner being controlling? Are they just clingy with each other, or are they insecure in their relationship? Do you think they need to learn to let one another go, just for a few hours at least, or doesn't it bother you as long as both people in the relationship are happy? Do you think it shows that there is a lack of trust in the relationship and that one partner always has to know the whereabouts of their partner?
