I was in a similar situation. I was intimate with my boyfriend. I kept telling myself I wouldn't do it again. But everytime I saw him he seduced me. I knew it was wrong, but he didn't care. I finally had to choose either him or CHRIST. I chose CHRIST & never regretted it. I have no contact with him anymore. It's been 3 years. Occasionally the devil tempts me with thoughts, but I know serving GOD is the best way.
