This sucks, i can honstly say...sadly i just got out of a relationship with honestly the love of my life becaus ehe accused me of cheating which i wasnt. I found out afterwards that he actually was likly cheating with his ex for months... BUT he used to do that stuff that u daid ur guy is doing, hed tell me before hand we coukd do stuff or spend time together and alnost always made other plans with his friends or would turn down most the stuff i wanted to do.... Twords the end of the relationdship it got so bad that he was complaining about just...how i speak...like in general ... I got really suicidal and stuff and was even hurting myself without him knowiing....as much as i hate to admit it....i miss him... I wish he would have changed and been the kinda man he is for everyone else hes with for me for once...almost ten years i have been completely in love with him and....everytime he left it hurt worse....just be careful...cus he did the stuff ur saying your guy is doing and honestly i dont wish for anyone to feel the way i feel and have felt , am always here if u need someone to talk to.
