You have couple goals expectations
Couple goals are based on an unachievable ideal. We've been shocked many times that some of the most popular 'it' couples like Bill and Melinda Gates or Brad Pitt and Angelina Jolie split up and still, we, find ourselves comparing our relationships to couples we don't really know.
There are many ups and downs that every relationship goes through regardless of how many amazing photos they post online. This is something you need to remember if you tend to put unnecessary pressure on yours.
You're constantly searching for relationship advice online
The internet is a place that offers us advice about everything under the sun. Unfortunately, a lot of it is bad advice and you could end up ruining a relationship that had potential.
If you need to hear real advice, consult someone who is older, is full of wisdom, is successfully married or is in a long term commitment and they know you well enough to tell you the truth and pinpoint your short fallings. This is better than filling your mind with unrealistic advice from random people all the time.
You think you're the perfect catch
It is good to be confident about what you bring to a relationship. However, you can easily cross over into an egotistical kind of thinking especially when you're not honest about your flaws.
So, if you believe that there's nothing you need to work on or that it's always an ex's loss whenever you break up, it's a sign.
