What should I do?

Start by praying from now on for your future life partner.
Make God’s standards for relationships your own standards.
Choose not to have intimate relationships before marriage and communicate your decision to the person you are dating.
Choose to stay away from the sin that defiles the body of Christ.
Do not fear the soul wounds you will receive as a result of a breakup, fear the sin that separates you from God forever, and fear a potential unsuitable marriage that you might end up in.
