I don't feel as though you should judge how much someone loves you by how much they are able to spoil you. I don't feel as though someone's love during your best times is an accurate indicator of how much they love you. 

If someone cannot love you during the most painful periods of either your life or the relationship, they are incapable of "love". If you truly loved someone, you would be willing to put aside your negative emotions in order to talk it out and solve the issue. If you really truly loved someone, you would be willing to come to a compromise together. If you really love someone, you would no blame them for something that hurts or effects them, because you should be able to understand that your significant other is another sentient being, separate from you and the relationship.  

If they are unable to do these things for the relationship, are you really doing what's in your best interest, or are you just staying out of familiarity? 

At the same time, you must reflect on yourself to see if you are also doing your part in the relationship.
