Ghosting is changing me, but am I alone?

44M Of course ghosting is abrupt no communication, but I'm also including a slower communication downgrade without an explanation.

I used to be someone who would fight hard to save what I felt was a healthy relationship for both parties. Of course the reason why there was a fight for the relationship at all was because the lady didn't agree with me, but those are stories for another time.

At first being ghosted felt horrible. Like I was having the lights turned off and I'm plunged into a despairing darkness. I have been ghosted so many times now that I've become hardened. I've had a lady be upset at me for not fighting for our relationship even though she was the one to kick me out. I've been ghosted so many times I have created sort of a mental check list of everything I can fall back on after I tell myself before I go to bed and when I wake up, " She may all of a sudden never say another word to me today and that is okay."

Meanwhile, I'd love to commit again. I'm just afraid I've become a little TOO comfortable with relationships ending to the point of me not showing much emotion about it.
