PLEASE TELL ME THAT I AM NOT STUPID!!!!!!!!!!!!!!!!!!!!!!!!…

My fiance and I have been together only about 4 mos. In that 4 mos before we moved in together.... everything was fine. WE moved in together last week and hell broke loose regarding an ex of his. I just found out that it was only 3 mos before we came together that he and his ex broke up. Then also finding out that he was still Living with her in a " totally innocent " relationship... and moved in with me from her house. I became crazed and worried. I called her and STARTED TO FIND out thins. I paid the rent to move in... and move in costs. He also spent just as much money on thins so that wasn't the problem,... the problem is that he found out i had talked to her and flipped out. He wanted to make sure it was her I talked to... and for example... when he described her... he talked about how pretty and hot she was, how he paid for bot-ox, how skinny she was, how she had fake , lon dark hair to the middle of her back, etc... and I was really hurt. I had to see how wonderful this person was,... and I Am not sure why. So I kept prying and poking. After his description of her I was sure he still loved her and he told me that he did. He also told me that he still loved his other ex-wife. He then told me that he loved me and thought I was pretty also. For some reason... that didnt fix it at all. So, I kept up my pryin, etc... Last nite I Came in and was very emotional... I was cryin and upset. I told him why. He was bein told why I was pryin. He wasnt even thinkn about what or why I was doin that... he was talkin about what she did to him, her job and how it was lop sided, how she pushed him away, and he did keep sayin he was sorry for doin that over and over. ( BTW... my computer letter jee) doesnt work. HE woke up, put his hat on... left sayin he would be riht back and he didnt come back. he wrote me a text messae that I lied to him... that he was done to me... that i never talked to his ex,... that I never paid the rent, the utilities, etc... he refused my calls and wouldnt talk to me. I found him at his istants ( work ) house. I did nothin bad... didnt yell, NADA! asked to talk to him and he called the cops on me. His istant texted me and told me that he just needed to cool off. His istant then texted me and told me that he wanted to come and pick up somethins that he was oin to a motel for the niht and that he didnt want me there or the kids. I told him that I would wait upstairs. Heg came in and picked up stuff. left back to istants house. told me that he would talk to me aain tomorrow... told me that he didnt want me ever textin his ex, callin, emailin, etc... I am home on Valentines day alone and very sad. i feel like a rebound. Please dont attack me for being dumb, or attack period!!!!! ok??? just want to hear some opinions to help clear my head.
