Why does a girl say "I love you" like it's not a big deal?

Some girls are just that desperate to fall in love these days so fast, which is sometimes can ruin a relationship and it won't last, sometimes they do last. If she's already posting kissing pictures with "I love you" after dating one day, then she's not mature yet, and not clearly thinking about her actions. Some people have issues within their lives that cause them to cling on fast to people and others know how to wait for it, trust has a lot to do with this. My boyfriend and I met, we dated for a while then he asked me out and it took him months after asking me out to say "I love you", he said that he didn't want to say it if he doesn't mean it fully yet, which I respected because I'd rather it be real than just thrown out there "I love you". He dated other girls before and said it but he never really cared about them. I've been together with him for almost 4 years. Saying I love you is important, some people do say it to their friends because they care a lot about them and have known them for a while, so there can be "love" there and that's ok because some people aren't dead serious when they say it (more as a friendly thing to their friends). I do reserve "I love you"'s to my family, boyfriend and his parents if they say I love you to me, and that's all I say it to because those are the only people I do love and care about the most. Hope this helped a little on my opinion.
