URGENT [20M] Should we break up?

We've been together for 4 years.

She loves me; shes willing to keep working at our relationship despite how much we've been fighting

I love her, but I hate how much we fight and I'm worried that we're not on the same wavelength we used to be

She talks to her friends about our fights, and they say its just a period and that we'll get over it

I talk to my parents and friends, they say it's time to go

When we fight, she cries. I feel sick, but not sad. My head goes cloudy

I cry when I think about breaking up because of how it will hurt her

We conflict almost every time we are together, and it gives me anxiety.

This morning, she called me and we talked. Shes waiting on me to call her back and break up or make amends
