Sorry to burst some bubbles, but the answer is mostly B.
Not saying you won't love the same person (everlasting), but that love- is always a-changing.
It can be lusty, drastic, dull, gooey, passionate, sweet, sour and sometimes stretches thin.... and sometimes it's all that in just one day. It can be tiring but yet you still work on it if it's important enough to you and you're getting as good as what you give.....😍
