Help I'm lost😒😩

I think I'm in love with this guy but he broke up with me and I act like I don't care but I do! I want to get over him but I can't! I think about him all the time.. I spent a week with him and his family and we wasn't together but he said he missed me and so we fucked like 6 times and he text me and said what is in the picture.. Was I fucked and left? How do I get over him.. We have dated before and it was the best times I miss him so much.. But I think he used me.. 😩 After we fucked we was a couple and we never argued that's the weird part😒 he did find out that I was talking to a guy before me and him but that's not a big deal.. We stop talking before we fucked but I'm just lost and need help..
