be careful about people online as lonely women

So i met this one guy online and we talked for months. He always ranted about being lonely and unattractive so i could relate to his pain and his sturggle with his mom ( just like me) i offered too much empathy for him and got attached . he was also TOO GOOD to be true, he would listen to me like nobody else and compliment me but that was till he started asking stuff ( i don't want to say what you imagine what someone on the internet can ask :P ) and would manipulate me into doing what he wanted. I did it because i really really liked him.

Then he started ghosting me, finding excuses to not talk to me and when i tried to cut him off he'd beg me as if i was his wife for 10+ years.

side note here his attention was consistent for some months but that changed as the time passed. He also claimed he had no social media, no whatsapp ( cause he said he used an old mobile phone) i was convinced because his pictures looked like they were taken from very very old device.

Sooo he eventually ghosted me. That of course made me so so heartbroken. After this experience i cannot trust men online. I've gone through so much pain and i was too embarassed to tell this to anyone because it was so silly to fall for a man you have never met and never even face timed. Please if you read this, don't get attached to people online unless you meet them in real. Because we are lonely and easy to taken advantage of. Hope this helps to some people here.

EDIT: forgot to add an important part, my experience shows people can show GREAT effort to get what they want, i needed to learn how to say no and when to let it go. It's very important to protect ourselves
