Husband's brother may have impregnated me

I've been extremely depre and disgusted for hated every inch of my body for weeks. My husband and I have been married for 4 years and I have always been opened to the idea of having kids. Me and him have tried for 2 years and nothing and he refused to get his fertility tested. I found out I was pregnant almost a month ago and was super excited just to find out HOW I probably got pregnant. I found a second phone under my husband's side of the mattress. When I went through it at first I saw videos of porn on this phone which I honestly could have gotten past but then I saw text messages from his brother going back MONTHS ago. About how he had a vasectomy and he's worried I will find out and he doesn't have the money to reverse it. He asked his brother that if they got me drunk if he would have sex with me to try to impregnate me and his brother AGREED! I had been over his brother's house two months ago and I remember passing out after one near and one cup of wine along with some weed. I don't remember anything but that's when my husband drugged me. I called him screaming at him at work and went and packed my stuff. I was gone when he got home. He called me to talk to me and he was crying saying this was the only way he could give me a child and he thought he was doing the bad thing. I asked how was drugging me and letting his brother rape me a good thing and he told me not to think of it as rape. It was him sacrificing his wife being with another men to give us a baby. I said there is no baby because I'm getting an abortion and I want a divorce. He's been begging me not to get an abortion. Today is the day I took the abortion pill and I was honestly just crying. Not because I want the baby because I don't but because the reality of what happened to me as set in. I made the mistake of telling my parents. They are extremely religious and anti divorce and think I need to make things right with my husband and alsi tried to talk me out of the abortion. I'm currently staying with one of my friends from college because I had nowhere else to go. Everything is sinking in. Idk why it's taken minute to sink it but I feel so alone. I have to pass this baby on my own. My parents aren't on my side. I'm just alone...
