Perhaps you're being forced to think about the subject and are desperate for an answer regarding your situation. It's unlikely you have the luxury of reading numerous books on the topic or the time to talk to a wide cross-section of counselors. If you did you'd discover that there are various interpretations of the relevant verses. Maybe each opinion covers its own unique situation. However, God has a straightforward answer because it's important. You must choose the best exegesis for the right solution. You have the help of the Holy Spirit because "His anointing teaches you about all things, and is true and is not a lie" (1Jo 2:27).
This booklet is to stimulate thinking and to shorten the discovery period. Otherwise, you may become disheartened when you come across interpretations such as "the Bible says its adultery so you sin if you do such-and-such." There is enough guilt already and a person honestly seeking answers will be further depressed by legalistic pronouncements which communicate condemnation.
