If you find it difficult to forget everything now, it is uncomfortable to stay in a familiar place. Why don't you find a place where neither of you has been and be alone? You can also spend more time with your family, or have a heart-to-heart talk with your friends, and talk about your troubles and pains with your family or friends, and your heart may be slowly untied.
A simple trip can make you as relaxed as possible and forget those troubles. Especially to those places with beautiful scenery, it is best to be with friends, so that we can help each other and have someone to talk to.
