DOES IT EVER GET EASIER

My ex boyfriend and i just broke up a few weeks ago and I didnt see it coming. We got into an argument about him bailing on plans again, which he did oten. I always felt like there were always excuses or more important things or people. I got upset because he wanted to bail again and I think I overreacted a little bit but once the fight was over I told him to go for a walk while I make us dinner so we could blow off steam and cool off. Once he got back I sat the food in front of him and sat down and sincerly apologized for gettig upset but he wasnt having it. He had called a girl to come pick him up two hours away. I wasnt really sure how long it had been going on but he said they are just friends.. After a week of being broken up we met up to talk about something serious and he was already telling me he was trying to get another girls number. I had a panic attack and could barely move or breathe. Im so in love with him. He  was telling me things last week about making a mistake and leaving and care about me and love me and I wanted to believe it. Then a few days after that he said it wasnt the truth that yes he does want me in his life 100% but just as a friend. I dont know what to think because even the day before we broke up he told he how much he loved me and how much he cared and that he could never actually leave.. I have been trying to keep my distance becuase it hurts so much the fact that I care so much and am still in love with him and he doesnt seem to be affected by this break up at all. He tries to call me sometimes i havent answered and also last night he said to me that i didnt have to ignore him and also asked me why i blocked him on social media and asked me "youre really just gonna leave me alone?" "you dont want me in your life at all?" "okay then." what does this even mean? I NEED ADVICE? Does it ever get any easier or better. Was anything he ever said even true? Or was everything a huge lie?
