Marriage and its hardships

I see so many women on here who are married to men who are unfaithful , liars & abusive .

I've seen everything from the men sexting women , physical cheating, and abusive behavior .

It honestly scares me ... You know .. Marriage . I always thought that it was so sacred but I hear so many stories from friends and people on here that prove otherwise .

It seems so common for a marriage to be like that . It gets better right? Should you always fight for your marriage ? No relationship is perfect not even a marriage ... How is a marriage even supposed to be . Is it even worth the pain?
