Don't think that people who step out on their partners have no idea that what they are doing is way out of line. They know that the relationship might very well come to an end or become completely ruined after an affair.
Don't be hasty to start a relationship you aren't ready for. Wait for your true love, and it'll come at the right time. When that day comes, you'll meet the perfect soulmate you've been waiting for for so long.
