Why can’t I get over him?

So my ex and I broke up almost 2 months ago & we haven’t talked at all in nearly a month and I’m still having a hard time getting over him.😣 I constantly keep thinking about him. I’ve been trying to get out, I’ve been hanging around family and making new friends but I still can’t fully move on. I’m so frustrated because he’s moved on with his life not worried about me and I still cant find the strength to completely let him go. I know it takes time but I just wanna stop thinking about him so I can move on with my life. I blocked him on everything already so I can’t see his posts. What can I do to help this easier? Every time I feel like I’m getting better, when I’m alone or randomly through the day I start to think about him. I miss him like crazy. I keep reminding myself of all the things why we broke up. I tried going out with other guys but I don’t want to throw myself into someone else right now. Please help me ladies, I’m struggling😩😭
