I was wondering this with other couples because i just got done fighting and arguing with my gf...it was on the phone, it lasted about an hour, and it was over something she said. We ended up settling it before we got off the phone, Thank goodness
After thinking about this, i think my gf and i fight/ argue about once or twice every 3 weeks...its never over anything serious...just over stupid stuff, we know its over stupid stuff but we still do it anyways. Its all good at the end tho
