Love everyone ? yes but humans or even animals are not really meant to stay together lifetime . why ? we all love and want change and that is fundamental nature of universe . Every one gets bored . Together in Highs and low may not be a problem but change is must even when we are together . Even if we dont like , the entire universe is made for change . So not to crib , keep meeting more people , love every one . keep together till comfortable and change when not should be the game . But never get sentimental is the key .
