So confused and falling apart at the seams

So confused and falling apart at the seams. Met someone early last year (online) who always insisted that I was the 'other half of his soul'. As if to convince me of that, from the very first day, he began telling me things about myself that were impossible for anyone else to know, including my family. It was a deep, deep shock. No one has ever 'known' me. Then I discovered he was no less than 3 decades younger than me and I ran from him. Repeatedly. He always caught up with me and wouldn't buy my reasoning for the valid point it is, always admonishing that it was an "unacceptable excuse". I kept running; he kept pursuing, always telling me how sorry he was that he hadn't been there for me and that I'd reincarnated too early; that he should have found me sooner. At times, I fell for his words and his promises, but mostly, I'd run and when running didn't work, in the end, I attacked him with venomous words in an effort to rid myself of this bizarre relationship. Why? Because even I began to believe it and as I did so, was aware that I was setting myself up for a fall. The fall came when I discovered he lied to me for a very long time and had actually moved in with another woman, undoubtedly making the same promises to her, saying the same things, using mental 'trickery' to suck her into his web of deception. Because of this, I will find it hard to trust ever again. And so help me, if another man comes along and tells me I'm his "twin flame" or the "other half" of his soul, I shall hit him over the head with the heaviest thing I can lift! This betrayal of trust was the last of many in my life. I cannot afford to go through it again. And I shan't. How can anyone possibly be so devious? ...Non Twin
