Love is not incompatible with connectedness. The very way of the world is love. So people who are alive cannot exactly not be "unified".
But people do what I described because they have different destinies than you. It takes them a long time to come to know facts because they can't understand or accept what you had to open your mouth to tell them right off the bat. The reason is that we, who are ordinary people who are not enlightened, do not really recognize the causes we carry within our own consciousnesses. We only witness results/effects and don't fully perceive the problems that made them become that way. So even if you could predict the future people can't accept what you say without their own verification.
But people only take exactly what they are ready to take even from a perfect teaching. Basically, people hear what they want to hear. Plus, it's really arduous to change for the better in most cases. So people who have such things in them have to distance themselves from you if you retain your sincerity as it's hard for them to stay near a person who doesn't agree with their expectation that they're right. Their pride feels hurt.
Eventually, if your words were true (true love), then they have the chance to come to know you in the future, after they confirm and experience lots of things through their own living. But it's hard for them to reapproach you if what they have done made Karma inside of their consciousness. And that's provided they don't destroy or lose themselves in the process.
