This day and age all I see is arguments growing as time goes on in a marriage.
Not all marriages are marked by arguing. In fact, there is now really good research and information that can help you navigate creating a great marriage. The thing is that marriage takes a lot of work by both spouses. This work is primarily internal - it's about each spouse being obedient to godly principles (mutual service, selflessness, and submission; humility to put the other ahead of yourself, and taking control of any negative thoughts that feed resentment, nurturing the good, and a host of other principles that take a lot of work on yourself).
I am the type of person who walks away from drama good or bad. Maybe it is perhaps I like a person and it did not work out. I don't see how people do it. I have noticed over the year people distance themselves away from me but I don't care because I am not changing for anyone anymore.
It sounds like you are disillusioned and hurt by your experience. Relationships hurt...when we make ourselves vulnerable and give another person influence in our lives. In fact, to the same level we can experience joy with someone, there is the capacity to have the same level of pain with that someone.
You do not need to change for anyone, and you shouldn't. There is only one you should change for, and that is to be transformed to the likeness of the Lord Jesus. If someone does not accept you absolutely the way you are -and the way you will become - then that person is not someone to stay in relationship with. The "right" person (includes you being the right person) is one who will commit to care for the other with consistency even as the relationship and the people in it grow and change through the years. When you are in relationship, you will change along with the other person - it's about the process of the two becoming one.
I see it on relatives's eyes when I tell them I am remaining single forever. I have had women who were interested baffled... No one seems to understand. Perhaps all one need is FWB or something and just move forward in life...
FWB? I don't recommend it for a number of reasons, not the least being bonding. "Benefits" causes hormonal interaction that creates bonding, and iirc, women have a little more bonding going on than men. FWB breaks hearts, and the Bible tells us to guard our hearts. Another reason is that the Bible warns us against fornication (sex before marriage) and adultery (a married person having sex with someone not their spouse). As believers, part of what makes us a follower of Christ is to align our will with his - including sexual purity.
Otoh, current research supports the "friends" theory of making marriage work. We treat our friends a certain way - we love and accept them, including things we disagree about. We respect our friends, turn to our friends when we need help or support, our friends give us a sense of belonging. These are all things we should have in our marriage; things that make marriage work. But it needs to be worked at....selflessness is most important.
To answer your question - is marriage worth it - yes, absolutely worth it when you find someone who is just as committed to learning to love you as you are committed to learning to love her. When you are both in it to put the other ahead of yourself, it's sooo worth it!
If you ever change your mind and decide you would like to find a partner, it is a good idea to study the relationship Jesus has with the church - things like "God loved us while we were yet sinners....", "he gave himself up for us", and concepts like his ministry (reconciliation) and his nature (love). When you study Jesus' relationship with the church and are prepared to do this in a relationship with a wife, then marriage would be a consideration.
