Love is definitely a really wonderful and important thing to experience in life. It has its ups and downs for sure, so never assume it's all roses!
The important thing with love is that it should grow over time. It may fluctuate but it shouldn't die. It leads to people developing a life together and can have it's times where it's challenging but overall it should be the best thing we can have in life, despite all of the bullshit in the media that tells us it is not.
