My (F26) boyfriend (M32) has been using me for my money.

My ex-boyfriend and I broke up about a month ago, after being together for two years. I'm tired of keeping this secret because it's all I can think about, and I'd rather not share with my friends and family so I'm sharing it here. We started dating during the pandemic, and even moved in together at the start of 2022. Initially everything was great, he was thoughtful, caring, and I loved him for it. We never really shared our finances but he's also a software engineer so I didn't worry too much about it as it seemed like things were going well. I'd met his family and we talked about a future together, but I started to notice some small changes in him this last year. He became more withdrawn, it became harder to get him to open up about things (we had to force him to tell us what was wrong sometimes). We had our disagreements like any other couple, but we rarely had actual fights, and I thought we had gotten past that. However one night we got a notification from one of his credit monitoring services that his credit score had dropped. And when we looked at it together I saw his credit card statement. It was in the thousands, and I pressed him about it, trying to understand how he had managed to rack up such a large bill. He became defensive and said he had been buying essentials with it. I called him out on it and forced him to show me all of his statements. I was in absolute shock when I saw how much debt he had accumulated. He was paying two mortgages, two car loans, and had multiple credit cards. He was also using my credit cards, and had spent thousands on them. I immediately broke things off with him, and we fought. He argued that he had done all of this to provide a better life for us, he had been collecting unemployment and using my card to get his finances in order. I wanted to believe him so bad, but what he was doing was inexcusable and I couldn't forgive him for spending my money. His debt is over $150,000. I feel so blind and naive for not catching on to this. He owed so much money that when we broke up and I kicked him out, he had to move in with his parents. He still had the audacity to email me the other day, saying he missed me and wanted me back, even offered to do couples counseling. I want nothing to do with this man anymore. I just want to move on from this and feel as confident as I did before.
