Life’s a journey and sometime our hearts break because other value us differently then we value them. Sometime everyone wishes we can have that euphoria love last forever, but it may just be infatuation and then the SO chooses to start their new chapter & close your chapter along with lies and/or NoContact type behaviors. Best to remember the joy but also remember most pain because of happiness with passionate lust not love. But best to wish both real happiness for futures & move on to seek actual healthy minds/spirits. Can sometimes be a blessing in disguise that you’re not together & could’ve been worse for futures. Both deserve to be happy in their futures. Let teem go and you chase an actual healthy relationships just be single without attachments. Idk. Best of luck to you.
