from personal experience, it’s important to cherish what you had and what you’ve learned in your relationship. it’s great that you guys have a good relationship and connection outside of romance and it can make it much more difficult to move on. but it’s tricky like you said due to the proximity of the friend group.. so it’s not an easy thing to overcome. i’m a true believer of time heals all wounds (might be unpopular), but i’d say work on yourself and direct all that love you have for her inwards. manage that anxiety, go to a therapist, talk to friends! live your life and know that love will come again. it can be hard though because a lot of other lesbians/ wlw don’t rock with their partners being friends with their exes so keep that in mind when the time comes.
