Help!! Split up😭

Gaby
I just ended things up with the guy I was talking to. I have never had a serious bf. We were going out only for three months and I thought it was all going so great. He told me at first he didn't want a serious relationship because he had just broken up with his ex. I agreed but I ended up liking him a lot (One of the reasons we split up) but he didn't want anything just yet. 
I have lost my appetite. Does anyone have any tips to move on and let go?Â
