First off, although I do concur with your point of view on this site, you're kind of generalizing this site just a tad. It's the people that you meet from the site that makes the site worthwhile, not the site in of itself. sure, there's plenty of morons and idiots within this site that can cause such a generalization, but just try to be a bit more open minded about the sites you go to, and I guarantee you will have better results. Just weed out the idiots along the way.
Regarding relationships, as the other already have indicated, too much of anything isn't good for you. Especially being around your significant other for too much of your time. It make you look VERY clingy and needy, which is not a good look at all. Every person needs their alone time and space and their mates must respect or that will be the first sign of a relationship going south really quick.
