To have a causal relationship that includes intercourse with someone back in the day they were force to marry and the man would have to take her in as his wife. In other words, if you slept with her, she became your wife; that was true back in Bible times and in some cases is still true today. That's why intercourse is the bond & beginning of marriage. The bottom line: Don't sleep with someone you don't wish to be married to. (Deuteronomy 22:19-29) take the time and read it! Don't judge anyone especially if you haven't walked in their shoes, don't accuse anyone especially if you were not involved in the relationship or not an eye witness. If Engaged: be engaged and get to know the person you about to spend the rest of your life with, date them well./If Married: be devoted, caring, loving, sensitive, kind, listen and speak up when it's your turn, share all of you not part, find a way to make tomorrow better than today for your partner, give and receive alike, if a provider provide your best, if the home keeper, do your best/If Divorced: fix it with God's help, if you know what you did was wrong go to your partner and fix it and if they are not willing and you can't get them to go to counseling and you've done all you can to find reconciliation and it still can't be put back together? Depart in peace.
