If arguments just started for no reason, then she was looking for a reason to get a "break" and somebody else was in her ear...
But it's all good homie. Just don't sweat it and she'll come back around. If not then it wasn't meant to be. It might take time but you'll get past this
women emotionally detach weeks, months even years in advance.
It's never a spur of the moment thing, its why you can cheat on a woman and she'll dump you on the spot but the majority will come back shortly because logic tells them to dump you but emotionals override it. They need to emotionally detach, and once they emotionally detach they no longer care anymore. It's why they can literally go from being in love with you monday and on tuesday feeling absolutely nothing for you, its why they can text and call you every day for years then when its over don't even feel the urge to call or message you, they are so far ahead, you've already died and they mourned the end of the relationship while they were kissing, hugging, sucking your dikk, and then when they are healed and almost over you they drop them thangs, the arguements the I need a break etc. etc. your left dumbfounded because you didn't see the signs , you think deep down she will come around that what you hd is special but nah its already dead, she's prob on tinder or pof, or has he reyes on anaother nukka
