You know, a long distance relationship doesn't have to be a failure.
I've been in a long distance relationship for almost 5 years and we're still madly in love, we still talk on the phone for at least an hour a day, when COVID was raging we wrote daily letters, did video chats... if the two of you are motivated enough, both of you - it can be done. It requires effort but honestly so do all relationships and it's not a "chore" to talk on the phone and make time for him each day, it's a joy.
If you really love each other, it doesn't matter whether he's physically present, so long as he's emotionally present. You may even discover a spiritual element to your relationship.
One of the most famous love stories of all time (Antony and Cleopatra) involved periods of YEARS when they were forced to be apart and could only communicate by letter.
World War One and World War Two veterans had their long distance sweethearts and a large percentage of them came back, got married and stayed married their whole lives.
Don't let a statistic about LDR define your life without at least TRYING if it's something that you want that much.
