Guidance for relationship

My best friend's sister recently ended a long-term relationship and, against our better judgement, we started dating. After realizing that we had rushed into things (based upon a mixture of how fast the relationship seemed to move and my fear that she was transferring lingering feelings and expectations for her ex onto me), we agreed to "take a break" and try again later. During these few weeks I have begun to feel that despite our past friendship and mutual interests, we aren't compatible. The problem I'm having is that she very invested in making our relationship work, I don't want to hurt her, and I told her we would try again. She doesn't have any real friends aside from me and her family doesn't support her in anything she does (except for the relationship with me). I understand that doing the right thing will be painful and I have been praying for answers and the strength to act. Do you have some Scripture to help me or some words of wisdom? Thank you.

If you told your friend that “we would try again” and you do not intend to follow through on that, you want to confess your shortcomings and seek her forgiveness. Your friend deserves an honest explanation.

Are there Scripture passages applicable to your situation? These passages come to mind: “Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you” (Ephesians 4:32). “Therefore each of you must put off falsehood and speak truthfully to your neighbor, for we are all members of one body” (Ephesians 4:25). “Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God” (Philippians 4:6). “Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone” (Colossians 4:6).

I hope these passages are helpful. God bless you.
