I Fell in love with a wrong man. 😔

Hi. This is what’s breaking me right now.. I fell in love with this man because of all the sweet words, promises that he told me. We ain’t really no each other before he approach me asking for my name and number. We texted and chat for a few days and I found out that he actually have a gf, which he also admit and says I am the one he loves and he can leave his gf for me. I trusted him and believed everything. And then last night he offered that will be S.O I said no. Because in the first place I already know What we have is wrong because im stupid i allowed it. And now he said to delete all the convo or even his number. Just like that? He left me hanging.. i don’t understand and i fell so broken and crying my eyes out the whole night.. i hate myself even more for believing all he said. What sucks is. Were neighbors.. what should i do? I hate him so much now. He just give me false hopes and me being stupid still hopes that this day he will talk to me again. I don’t know what to do anymore. He even blocked me in fb which really frustrate me and my ego. I am not desperate to force him to be with me eventhough that is what i really want to do. But does he really have to do that? 😭
