writing a physical letter to my LDR boyfriend 💌

Is writing a physical love letter and mailing it to my long distance boyfriend a good idea? Me and my boyfriend have been together nearly 2 years as of December 4th this year and right now me and him are kinda on break due some issues we both have and the fact we live far apart from eachother we still both love each other very much I wrote a letter to my boyfriend about how really feel about him and also how our long distance isn't going to be forever ect right now he's living at his parents house in the middle of  nowhere and we even talked about living together at some point
