Well loving oneself is paramount. I agree that in part when you have offence with someone, God put a mirror in your face. Sometimes we ned this to happen a lot before we get the picture.
Then again what is Love?
1Co 13:4 Love waits patiently; it acts kindly. Love does not envy [or, is not jealous]; love does not boast; it does not become haughty.
1Co 13:5 It does not behave disgracefully; it does not seek its own [things]; it is not provoked [or, irritated]; it does not keep a record of evil.
1Co 13:6 It does not rejoice over unrighteousness, but it rejoices with the truth.
1Co 13:7 It puts up with all [things], believes all, hopes [or, confidently expects] all, endures all.
1Co 13:8a Love never fails.(ALT)
