Has anyone experienced a downgrade in their relationship with a DA?

My one started off love bombing, wanting to see me every week, messaging everyday.

Then a month in when we had the most intimate night (very emotionally intense driven by him), hours of talking, and then bedroom, followed by more talking and cuddling etc. he then flipped a switch the next day, faded me out then ghosted.

Came back after a whole month and made up lies as to why he disappeared (lied about someone dying) etc, I took him back. And since the hard ghost, things haven’t been the same since. No more pet names.

He makes plans but with months in between. But he usually will say “are you free on x day?” I go and we have an amazing time and then there’s distance again. I saw him a month ago, and then two weeks later saw he went on holiday with someone else and tried to hide it. I thought I’d never hear from him and that he had moved on.

Only a few days being back, This time, he reached a couple days ago at 3am asking what I’m doing. I didn’t respond until the morning and I told him I’d have needed more notice and offered an alternative day. He said he wasn’t able. I’m going away for two months. He didn’t even wish me a safe trip.

I’m feeling more hurt now that he went from making plans with me to trying to turn me into a booty call. It really hurts my feelings. The whole relationship has been chipped away to where I’m now just an option. A last minute scramble.

Has anyone experienced a downgrade from how they were treated in the beginning?

This isn’t my boyfriend by the way. This is a man who i thought we were starting out building one , and he tells me he is exclusive and monogamous to me every time I see him he lies to me to keep me around.
