If a married couple lives under the same roof, why one of them post this on social media?

If you read this on someone social media account, Could you say it is a way to say, he is having relationship problems? But the person do not say it directly he has issues with his partner but he posts similar messages like that on social media often.

The message says: "Sometimes you are not in love with the person, but with the proyect you imagine to have with that person and it turns out that today that person do not fit in that proyect"

Would that phrase makes you believe the guy is having issues with his lady? The husband of my cousin post today that on his FB account but as far as I know they are not separated or divorced, in fact like one month and fifteen days ago, they both had a family get together at a cafeteria to celebrate my cousins birthday and they both were there as husband and wife, but today the husband posted that on his FB account. I mean if you live under the same roof with your wife, why he posts that? My cousin used to have social media one year ago but she remove her account like 6 months ago. On the contrary the husband does have but he posted that today.
