If anyone is worried that he might not be acting honorably toward the virgin he is engaged to, and if his passions are too strong and he feels he ought to marry, he should do as he wants. He is not sinning. They should get married.
References for 1 Corinthians 7:36
But the man who has settled the matter in his own mind, who is under no compulsion but has control over his own will, and who has made up his mind not to marry the virgin—this man also does the right thing.
