According to relationship coach Marie Dubuque, when no longer feel the same way romantically as the other person in a new relationship, you should be sincere to yourself and not worry about the other person’s feelings.
It’s better you break it to them first than to let things build up between both of you. Waiting for the ‘right time’ will not make things better because there is no right time.
Many people end up in wrong marriages because they felt sorry for their partners and didn’t have the courage to break things off before everything became complicated.
If you don’t see a future with the person you are with, it’s better to let the person know than waiting for a long time.
