How to move on from someone who left you for someone else?

Sorry for a long post! My boyfriend broke up with me after one time when I tried to explain myself about my concerns in a relationship. He gave me silent treatment because he didn’t want to discuss it and went out.

It all started when one of his Chinese female friends invited him to a birthday picnic, I don’t know if it was just two of them or someone else was there too. He said this “my friend invited me to a picnic for her birthday” and nothing else. I asked about the details and he dodged the question and just said “do you think that’s a date?”. However, he remained romantic with me after that and everything was fine. Around 2 weeks later, he said it again “my friend invited me to a Chinese restaurant” and no details again. I tried to ask and confront him about it but he got mad and gave me silent treatment for 24 hours. My fault, sometimes I was a jealous girlfriend, and I could worry too much about his friends , especially girls. He never hung out with girls before. Only those 2 times.

So he went out with some friend (he didn’t say who, but I thought it’s the same girl, was afraid to ask). He got mad at me and ignored me and after that I gave him a call crying and begging for forgiveness and trying to explain my anxious attachment. Unfortunately there were several things he said that made me completely numb and unable to feel anything or be romantic with him. I couldn’t let go of the hurt and couldn’t go back to normal conversations we had and I got a bit cold and bitter. He got mad at me and broke up with me , saying that his feelings aren’t coming back and he would stay away from romantic relationships because it’s painful etc.

It’s been over 6 months since the break up and back then I didn’t even think of someone else, but now the pain got more intense and I started assuming he left me for someone. Even though he said he’s gonna “get a girlfriend years after”. How to get over this? I still love him and it’s killing me. Can’t think of anything else.
