The best piece of advice I got about relationships came from a homeless man standing near the road closest to my favorite restaurant in my college town. Me and my new partner of only a couple months were walking to this restaurant since neither of us had a car at the time.
We were walking by holding hands and talking trying to walk by the man without incident because many of them would harass us for money if we acknowledged them. The man looked at us and told us to remember why we loved each other and to always forgive whenever possible. He made it sound like we reminded him of the start of one of his most important relationships that he had before he wound up in his homeless situation.
Ever since then, I’ve attempted to remember that not everything that happens needs to be thought about forever. It is okay to forgive and forget and make a relationship work out long term.
Me and my partner have now been together for 4.5 years and I still take this advice to heart.
