It happened with me a couple of weeks ago. Yes, he said he liked me a lot, many and many times. I was not so sure, as like you I am on my fifties and I am not one of jumping into a relationship that fast. Then he was texting, not my kind of thing either. Then, he apologized, and I apologized. Something is not right when a relationship begins with sorry. I mean, once one is married it is OK, but in the beginning?
I take it as a red flag. Does it hurt? It hurts a lot. I cried and for a couple of days all seemed gloomy. But listen, it was not meant to be. It really does not matter if he is not into you or anything else. You deserve someone to make you happy, not someone to make you say sorry all the time just because you are who you are. Unless you have a big defect you don’t need to change substantially to please a guy. Because you will lose your self respect.
You should improve who your are for yourself not for a guy. Because in the end you will feel angry that you did so much for him. And that is also not good. Remain whole.
