I have a specific viewpoint about love that came from analyzing it very logically (beep boop). I started typing a whole essay for this post but deleted it because it was getting too long ^^;
Instead I will say that what I consider to be "true" love has nothing to do with emotions, relationships, or any particular person other than oneself. You can either just be a loving person in general or not, and that will manifest in all your relationships, romantic or otherwise.
Being vulnerable, respecting others, having compassion, laughing, appreciating, being willing to understand someone and to care - these are the kinds of things that make up love, but the capacity for these things is not dependent on any particular person or relationship. It's just you - how you choose to relate to yourself and to the world at large.
So I do agree that "true" love is very simple, if not necessarily easy. It's just that social norms, sex, people's likes / dislikes, and emotional attachments seem to make it all complicated.
