hi, i have a long distance boyfriend. can we be together forever? how to make our love grows strong?

i have a long distance boyfriend. we met in a social media year 2013, n we lost contact and recently we connect again n our love flourish, we exchanges sweet love messages but lately he seldom answer my messages. he was born on 0221/1957, n i was born 09/10/1963. were matured and have same experience from our past old relationships. i love him much, is he feels the same way as i do? he plan to live and retire in my country next year and perhaps do some investment.
Can we be together forever? how can we work on our relationship to grow stronger? i love him so much... how to win back his heart?
what is the future holds for us? thank u very much
