Scenario: guy/girl seeing each other for 3 or 4 months. First 3 weekends were great, then he cut down seeing her to once or twice a month. They talk/text daily. She is getting frustrated as he has cancelled the last couple dates. She asks him if he wants to do anything, he says no and is always busy. He told her that for this weekend too. She sent him a text this afternoon to say hi and he said he was out playing cards with friends. They argue quite a bit but neither will call it quits with the other. Why is it two people argue a lot but dont leave each other?
