Why I will not settle

I had a convo with someone this weekend and talked about how I feel about people who are with someone b/c they don't want to be alone or feel that they can not find anyone better. The thing that makes me slightly sick to my stomach is when those people decide to take these relationships and move them to the next step of marriage. There are a few people I know like this and I truly feel sorry for them b/c there is a good chance that they will never find true love which saddens me. Or they will end up ending there marriage. Both of my parents were previously married and even though I'm not a divorcee kid I saw what it did to my siblings. I have never settled and I NEVER WILL!
