What has happened to relationships these days?

It seems that all around me people are giving up on relationships. Nobody tries to have anything serious all I see on social media and tv is people hooking up or looking for just friends with benefits. Does anybody else ever wonder what they see in that? Like do they want that for the rest of their lives? I just got married 6 months ago to a man I've been with for over 2 years. Even though we have been together that long he still sends me sweet things like this message. Little things like this makes me so happy. I just don't understand why people these days don't want a relationship and to love one person for the rest of their life. I couldn't sleep around and be with different people and never have anything serious. I love my husband and I love all the things he does for me and how he makes me feel. Does anybody else think this way and see how it seems no one wants relationships anymore? Does anyone else blush and act like it's the first time their husband has done something sweet even after years of being with them?
