Relationship issues

I've been together with my boyfriend a year this Saturday! exciting I know, but all we do is fight and argue with eachother. I truly love him but how do I know when it's just not working anymore? we've been through the unimaginable together, but I can't figure out how to make the both of us happy and still be together. just need some advise and feedback😩😔❤️ we both love eachother but all we do is argue... it's beginning not to make sense.
