What the Bible Says About Relationships With Girlfriend
The short answer
When people search for Bible verses about relationships with a girlfriend, they often expect rules about dating. What Scripture actually offers is something deeper: a picture of what love looks like in practice. Proverbs 3:29 puts it plainly: "Don't devise evil against your neighbor, since he dwells by you in safety." The person nearest to you—and in a dating relationship, that is your girlfriend—lives alongside you trustingly. She has, in a sense, let her guard down. Proverbs says the one thing you must never do is take advantage of that.
This reframes what a good relationship is. It's measured less by intensity of feeling and more by reliability of character. Can she count on you? Do your words and your intentions match? Are you the kind of person in whose presence she is safe—emotionally, practically, in every way? Proverbs treats scheming against someone who trusts you as one of the ugliest things a person can do, precisely because trust is the foundation everything else in a relationship rests on.
At the same time, Proverbs is not naive. The same book that praises trustworthiness also urges discernment about whom you trust. Both halves matter for couples. You are called to be openhearted and dependable, and you are also called to use clear-eyed judgment—about others, and honestly, about the person you're dating. A relationship where one person is endlessly trusting and the other is careless with that trust is out of balance.
Interestingly, differences in temperament here aren't a flaw. One partner may be naturally trusting, the other naturally cautious. Rather than being a source of conflict, that difference can steady a relationship, with each person supplying what the other lacks. Wisdom, in Proverbs, is often like this: not one right personality, but two people whose strengths cover each other's blind spots.
What scholars say
John Goldingay explains why Proverbs treats trust as central not only to our relationship with God but to our relationships with people—offering a memorable definition of love and a personal glimpse of how differing temperaments around trust can complement each other in a marriage.
“The other reference to trust comes when it talks about the neighbor who is living trustingly with you; you’re not to make some plan against him. One definition of love is making the world safe for the other person, who can then know it’s possible to count on you to do so. So trust isn’t only key to our relationships with God but key to relationships with other people. My father was a trusting person, and my mother sometimes despaired at the risks he would take in connection with other people. I follow my father, whereas my wife is like my mother. The complementarity in both marriages is good; Proverbs has already given good reason for discernment about whom you trust.”
What it means for you
If you're dating someone, the question this passage puts to you isn't "How strongly do I feel?" but "Is she safe with me?" That means no hidden agendas, no exploiting her openness, no saying one thing and planning another. Becoming trustworthy is slow, unglamorous work—keeping small promises, being where you said you'd be, telling the truth when it costs you.
It also means using discernment yourself. Trust is precious; give it to people who have shown they can hold it. And if you and your girlfriend differ—one of you quick to trust, the other cautious—treat that as a strength to draw on, not a fault to fix.
In context
Proverbs 3 sits early in the book, where a father passes wisdom to his son before the famous short sayings begin in chapter 10. The chapter opens with trusting God wholeheartedly (3:5) and then, in verses 27–31, turns to how you treat the people closest to you: don't withhold good, don't pick fights, don't plot against a neighbor who lives beside you in safety. The movement is deliberate—trust in God works itself out as trustworthiness toward people. Verse 29 is where that principle lands closest to home, in our nearest relationships.
