Have any of you ever been in a relationship and then ghosted the person?

I think sometimes when you meet someone during the honeymoon period you don't know who they truly are until they become comfortable with you.

The bread crumbing, emotionally abusive behaviour, hot and cold behaviour, push and pull, the gaslighting, the playing games with your emotions, the making you so anxious you feel like your walking on egg shells, withholding intimacy for three months saying it's due to low libido and the unexpected pregnancy which you terminated per their wishes the words you said after they ghosted you for six days and caused you significant emotional distress.

The repeated six days withdrawals, ten days now, three days there. From December to now I've experienced three periods of being ignored for six days, 3-4 periods of being ignored for three days, and one period of being ignored for ten days. Surely these people aren't that delusional that they think treating their partners like poo is acceptable. The good thing is I know he did this to others, because he told me he had only ever had relationships lasting a few months except for two or three which lasted a year each. He's 30 for context. I don't usually agree with ghosting and have never done it before but once I'm done I'm done. Did I mention I suspect he's cheating too and possibly monkey branching.
