how would you manage to tell someone that your falling out of love??

It is a very tough conversation to have, but one that you should get over with as soon as possible. It will be harmful to both of you to put it off. There is no doubt it will hurt, but if you are honest you will both be better off soon. He will get over it. It may take some time, but people are resilient.

Men in general are clingy people. I've had relationships and marriages where the man said all those things and how he'd never want to live without me and blah blah blah. Horse doo doo! They'll survive just as they survived before you. If you're married to the man, good luck! But, if you're just dating, then no worries. Just take a deep breath and tell him calmly, "We need to talk." That's the first clue that something's amist. But, be warned that he might want to try to do everything in his power to "bring back the romance". That can get very annoying and almost stalkish. Good luck!
