Of course, God supports your right to choose, I mean, after all, He gave you that right, but God does not support your every choice, but only your choices that aligns with His word.
YES IF U MEAN MEN WITH WOMEN...
The husband is the head of the family and the wife is the heart of the family. Marriage is between one person of each sex and is for procreation. It is not permitted for parents to give their children in marriage, i.e., to force, coerce or pressure them to marry without the child's free consent. Every person who has not waived the right to marry, e.g., by already being married, by becoming a priest, deacon, nun, sister, brother, consecrated virgin, etc. has a right to marry a consenting and eligible person of the opposite sex.
No, the Bible supports the relationships based on love and obedience to God and Christ and shows that relationships with ungodly people - end up badly.
Yes. There is nothing in the Bible that forbids friendship between any two people or group of people. Obviously marriage is clearly defined, as God defined it.
The Bible shows you of your sin and the only Saviour from sin.
Depends on what you mean when you say "free choice".
In order to answer that
I'd have to know what "free choice in relationships" means.
From beginning to end. But, divine judgment for those choices remains a certainty.
I think so. If you read what God wanted from Hosea, you might realize that God could have his own ideas about who you have a relationship with.
