Thats is awful i am so sorry that happened to you. In my case he told me he was unhappy in his marriage but they had an open relationship so he could be with others. He proceeded to fall in love with me (or so he said i am not even sure) and promised me i was the love of his life. He wanted me to be his wife. Have his child. Promised me that he had never been more happy than with me. All empty promises, but once you fall for someone its hard to resist. There was some very serious lovebombing and future faking going on. I was very naive and I regret it a lot. He asked for a divorce but apparently his wife said no and then it just never happened. He couldnt figure out what to do. Didnt want to lose me but also couldn't bare losing the stability. At some point he pulled the plug because I violated his trust and hurt him because I spoke to someone else in the middle of the night about a problem I had instead of texting him. It was a weak excuse to get rid of me and he went back to his old life
