Friendship advice

c h a r l e e 🌸 • Ava, 28/03/16 💖 Twins Due March 2018 💙💙
I'm thinking of writing a letter on my blog to a past friend. We had a huge fall out around 18 months ago, nasty things said on both sides, and if I'm honest I'm not totally sure if a relationship is even salvageable, but I want to move forward and at least try, we both have children now and I feel upset that we no longer speak. Is me writing an honest letter a good idea?
