No, do not continue a relationship even if you are not in love with your partner. If you continue the relationship, you are being unfair to your partner and you are putting yourself through undue stress. Let your partner know exactly how you feel and work towards letting go and moving forward.
It is not good for you, if you are no longer in love with your partner and you continue the relationship, unnecessary fights will come up which will put you in pressure, unnecessary stress and exposing yourself to hurtful feelings. It's best to tell your partner the truth and help yourself move forward.
A relationship is a bond of trust between two partners. If you are not in love with your partner anymore, you are being unfair to the person by keeping them in the dark. They are devoting their pure love to you, while you are unable to create similar feelings for them. Eventually, these feelings will emerge and become difficult for you. You cannot live a life where you are not in love with your partner.
Fights, arguments and even hate can set in. it can extend to a point where the pain of living together becomes more than actually telling the person you don’t love them anymore. This is why it is better to come clean and let the other person heal, instead of dragging them along a useless relationship.
