It may also be thw case that Ay couldn't let go of thw thought of you and he desired that it could work between you two and so felt thw only way to ease himself was tell people yiu were his eventhough not so, hehe
However, the end is sad and I sympathise with you
Some people would try to destroy what they cannot have, Ay was sadly that type of person. And it was a bit too late before I realized that.
The end was not cool but I'm glad it is all in a long past now.
