Ex boyfriend problems

So my ex boyfriend and I decided to try things again. And they were going good until yesterday. He was like he wanted space last night and I gave it to him. And then he didn't text me all day and when he finally did we got in another argument and I was like do you till wanna do this and he was like Idk and I was like it's a yes or no and he was like I don't wanna lead you on and stuff he said he lost feelings for me or whatever and it wasn't the same. But when we were together again all he wanted was sex and nudes, and he asked me to buy him a vape and stuff and then he just ended it with me and I started crying like he didn't care about how I was feeling at all. i was so confused on why. we had been on and off for over a year. like i feel like he was just using me even tho he said he wasnt .I just need some advice ladies to get over him and move on
