Relationship trouble

HAs anyone been through this with their SO & it ended up working in the end. I’m talking arguing, fights , mean words getting thrown, bad communication. Me & my SO has been going through it! I know it’s fixable because ofc there was a point in our relationship where we didn’t go through any of this & communication is key. It gets draining & tiresome sometimes but no relationship is easy I believe. I have a lot to work on myself & so does he. I don’t find any other guys interesting to me besides him. I can be looking at the cutest guy or whatever and I still don’t feel any kind of way or attraction like other girls😭. I know we need to talk & work on ourselves as well as have better communication but id like to know what’s a way to do this . I love our good times they mean everything to me & I fall in love all over again but during these times I not only love him but I hate him & hate myself because of all the trouble but it’s really just a temporary feeling . I know all of it can be avoided it’s really over stupid disagreements. We have been giving each other space as of now but when we do start talking-talking again what is a way to start the road to a better healthier relationship besides therapy because I don’t feel that’s necessary..
