Input: oh boy this is one hell of a story, but it's not terribly long.

well, I'm kind of the weird person that dates people online before meeting them. so I'm dating this girl, right? and we have been calling / facetiming each other and texting for a while now. about 3 months. so one day I told her "goodnight, sleep well! text me when you wake up" and she said "goodnight, you too!" and then in a desperate message she said something along the lines of "almost told you I love you ahah" I took this as kind of a hint that she wanted me to say it. so I kept that in mind. well, our conversation carried on despite us already saying goodnight and it being 3 AM. we were talking and getting really flirty with each other, like we do. but she told me something that she's been hiding from me- and rightfully so. apparently... she was married already. but she told me not to worry, and that they never talk any more and that her parents wanted it and that she didn't actually love the boy and all. it being 3 AM, I justified this. I brushed it off. at the end of the night, before we both went to bed, I told her I loved her- and I did. it wasn't a lie. but morning the next day I realized what she said. she's married. not dating someone else, literally married to another person. we were dating over the internet (with plans to meet btw)- how am I supposed to know she never talked to the guy. how can I trust her to be faithful to me if she couldn't to this guy- she said she dated him for four years before marrying him, and then she left him. how do I know she won't do that to me? I told her what I was feeling, and that I don't think I want to pursue a relationship and that we should part ways, and never talked to her again since that morning.

so reddit, AITA for saying i love you and then leaving, or is it justifiable being how easily manipulated I can be in the moment?

leaving my gf almost right after I told her I love her
