Do you ever look at people in relationships in social media and think that it can’t possibly end well?

I know that this is kind of a negative and pointless thought. Cognitively I'm not sure why my mind thinks this way. But whenever I see a couple post a lot about their relationship on social media, like maybe 3/4 of their posts are pictures or words about their relationship and bf/gf. I can't help but think to myself sometimes "this is not going to end well" or "this relationship is definitely going to end". I could be totally wrong and I don't think this way for every couple I see. And either way it doesn't matter and doesn't effect my life.

Does anybody else think that a relationship is bound to end when they see people overly posting about it or advertising the fact that they are in a relationship? Or is it just me?
