Walked in on **UPDATED** my boyfriend of 2 years with someone else

My ex and I were together for 2 and a half years and today I walked in on him sleeping with another girl in my bed. He yelled in my face to leave and threatened to call the cops, while I stood there and completely lost my mind trying to comprehend what was going on. I have never in my life felt so betrayed. He kept making me feel like everything was perfectly fine in our relationship. Said he just needed space so I went to my sisters house all this week and came home to this. Now I can't sleep or eat. I'm crying endlessly all day long. It's making me sick to my stomach. He did all of this knowing I had been in the hospital all week having kidney failure and still was going to work trying to save for our wedding. The worst part is, is that he is making it seem like this is all my fault. Trying to frame me as the bad guy. I could just use some positive thoughts and uplifting vibes. It would be highly appreciated. Thank you a million times in advance ladies.

***UPDATE***

I have talked to everyone close to me and they have helped me make an important decision. I'm going to chase my dreams of becoming a doctor so I just moved an hour away to my dream university and I'm so excited. It was amazing to see all the love and support my friends and family gave me. As for my ex, I went to our house at 5 am right after he left for work took everything I bought. So he has no bed. No towels. No TVs. No couches. No pillows. If I bought it, it was coming with me. 😊 I wish I could've been there to see the look on his face after a long day at work and having nowhere to sleep or sit except on the ground. Karmas a BITCH. 😂😂😂

Thank you for all the support ladies. I took each comment into consideration. It really hit home. I'm an intelligent, beautiful, and caring human being and I deserve the world. So I'm gonna give it to myself.
