Love isn't easy nor is it perfect. People will be flawed regardless of who you choose to love; it's important to remember that. You will always get into arguments or disagreements with the person you love, but if that love stays strong as well as your loyalty and commitment, then you will find a way out of those dark times eventually.
Love is not just a feeling; it's a bond that holds two people together through anything and everything in life that is meant to tear them apart. The ups and downs that we experience happen for a reason; there's always a lesson to be learned in every mistake we make.
I personally believe that relationships should be taken seriously because people have limits and true compassion is rare to find these days. Society has this warped view on relationships in general and while I get that some people aren't as old-fashioned as me, I still feel like humanity needs to get its act together when it comes to choosing a life-long partner. There is a difference between that and getting into relationships just for the companionship.
So in all of my experiences, I would say that love is worth holding onto in the end. Both people have to be patient, considerate, committed and compassionate towards each other through it all. And while there will be moments of pain and sadness, there will also be moments of joy and happiness. And while trust won't be easy to maintain, it's important to remain optimistic through those moments of pain and loneliness.
