Im good with being single

So I have had a conversation with a few people lately on why I have given up on Love and wanted to share it.
I would really like to be one of those people who does well in a relationship. Someone like my parents who have made it 30+ years together, but I just don't see that for myself.

Some think I'm a pessimist when it comes to Love, I prefer the term realist. Just taking a cross section of my friends (and there is no judgements being made just observations)

1-Best friend from college, moved to another state and lived with her boyfriend, had issues had to move out

2-Sorority sister, I was a brides maid at her wedding less then 2 years in and shes divorced

3-My own sister dated and lived with her boyfriend for 3 years before getting married, less than
2 years into that one, divorced

4-One of my favorite girls cousins from my dads side. Married and divorced with two kids before the age of 25.

5-Friend at work comes home early one night, after (i think) 5 years of marriage HES IN BED WITH ANOTHER WOMAN!!!

I could go on, but let me ask you this -
Who wants to try for a relationship, when all you see around you are people who claim their in love, but yet that love isn't strong enough to last more than a few years? Is it just society that makes us so anxious for something new? Are we jumping to fast into commitments we can't really make?
I just don't wanna chance my sanity on that. I want to be happy, I want a life that means something, but what I don't want is to waist my time on some fabrication of what LOVE has become.
