Noooo, don't say that my IX brethren!
Take it from the EF's romantic love pursuits can be gooey and light and fun or all consuming and drive you mad -- but I don't think they're necessarily a waste of resources.
I guess it depends on if you see romantic relationships and connections as worthwhile and meaningful in themselves or they are a means to an end or need to achieve X, Y, Z to be 'successful'. Or if there is some kind of 'pay off' buried within the other person and the relationship that you need to find.
I mean, the reality is that most romantic relationships end before the death of one of the partners, lots of relationships last several months to a few years if that. I don't think they're necessarily failures though if they end.
It's about the journey, Dana! The journey! And don't you like harelquin romance novels? Ha, no neither do I.
There are lots of kinds of love, and lots of ways to characterize and understand romantic love. At it's best, love is healing and transformational and about actualizing indviduals (like Sub mentioned) and creating something bigger than the sum of the parts.
As for resources -- yeah it does take a considerable investment and commitment to someone and the relationship for a you know 'serious long term relationship' and that is more taxing and confusing for some people than others. Some people are serial monogamists, being partnered is very natural and easy for them. For others, it just seems like a lot of trouble.
But even if in theory it sounds like too much trouble, when you meet a particular someone, you will naturally expend the energy and start making commitments because it's what you really desire. Basically, you want to.
