Need Relationship Advice

Look I know this isn't a place for guys but any guys group I ask always say "she's not worth it" and "there's plenty of fish in the sea". Lately it's seemed like my gf and I are arguing all the time and I hate it. Like I bring up something things I have questions about and then it blows up into an argument, then we make up and a fine for a few more days until it starts all over again. We don't actually see each other that much but we text and skype often. What should I do? How can I make it better? All of this has me in a pretty down mood😔 I just want it to stop! Once I get this stuff figured out I'm deleting my account so please don't feel I'm on here creeping, I just need some lady/motherly advice
