Yes I have had this happen..for 5 years...we were also just friends. He said he loved me all the time, although I wasn't really comfortable saying it back. I did believe him though. He bought me things, was with me when I had an operation, sent me cards in the mail, message me constantly through the day telling me every detail of his life. He even started seeing my Therapist (yes this should have been a massive red flag) I was his only friend that he saw regularly. Looking back I can see how he was manipulative and using me at every opportunity, but at the time it just felt really good to be 'loved' and the center of someone's universe.

Then covid happened, and he could no longer see or use me physically. So he stopped talking to me completely, and as far as I know is currently doing the same thing to another girl he works with at his new job.

I'm sorry this happened to you, it is really awful isn't it. I am not sure how we get over being so hurt, but I think we loved someone that didn't really exist...they were just pretending to be who they were. Maybe the only way to move on is to meet other people and experience true love and friendship, I hope this is possible for you. Even though I am finding it extremely difficult with the current social restrictions.
