Please help me move on

So me and my boyfriend broke up from dating for a year now... and he’s already dating someone else.. like did he even care. We have been texting recently and he finally said goodbye to me and he said he won’t ever talk to me again. If I’m being honest I’m crying while wearing the jersey he gave me and the necklace and bracelet he gave me:( I don’t know what to do. This last text said I was great and he was horrible. He told me to forgive him before it kills him... but he’s dating her. He said he can’t love me bc he doesn’t wanna break two hearts...

Please give me advice :(
