Always pray to the Lord and surrender your relationship to the Lord and be patiently waiting on our God. Also make yourself available for your boyfriend, but don't put your life on hold for him. If he feels that something good is missing in his life then he will come back to you.
Perhaps you can plan to spend every evening with him while he's at home during the season, or maybe he can bring you along on a few of his away trips. So many relationships are lost due to lack of comminication. I became who I am. I was independent, and on my own.
