Missing my ex badly right now

We've been broken up for about 11 months now and I'm dating someone else and so is he. My boyfriend lives like 2-3 thousand miles away and we've never met and I believe that he has no intentions of ever meeting me in person so I've started to stop caring about him, but I keep seeing my ex's family everywhere I go I seen his mom at my work the other day and then his sister who told me she misses me being around and it's killing me inside because this is the biggest secret I've kept from anyone because I want to just yell it out and say I miss him but then I'll lose my boyfriend and honestly I just want him to be my best friend now I'm so confused on what to do because I don't wanna throw my boyfriend away for someone who may not even want me. Any advice would be helpful
