What should I do and will he take me back?

ive been in a couple different types of relationships and i have to say i think the best thing is just to try to move on. I’ve had bed luck so just know your not alone. i went out with one of my girls friends for a year and a half and out of nowhere she said she doesnt like me anymore, and just like that…it was over, and while ive never had the vicious argument after breaking up, it hurts just the same, to know the one you liked so much can so easily stop caring and move on. again, i would try to move on, if he really liked you, he wouldn’t want to be i an open relationship. i was in one and it was hardly a relationship, just an ecuse for her to get action when she wanted to. if he wants to do that it could mean he wants to see what else is out there, a boyfriend should be devoted to one girl and same for that girl, in my opinion. it can be hard to move on but its most likely best, and if you dont want to, id say just try to show him he means alot to you, and if he ignores you after that, hes not worth your time
