My mother-in-law is trying to keep my wife and child from me?

I'm 18 and I've been with my wife for about 4 years but we've been best friends since I was 7 and we've known each other since I was 4, I guess. My mother in law used to like me a lot when we were friends. When we started dating, she tried everything she could do to keep us apart. She would "forbid" us from seeing each other, got my wife transferred from all my cles in high school, and even went as far as to introduce her to other guys when we were fighting. My "dear" MIL told me that I was good enough to be her "little friend" but not enough to be her man. My parents has hated my MIL since the beginning so they didn't want us together either. Our parents have done some incredible things to get me and my wife to break up, but they did not succeed. My wife ended up getting pregnant. It was a total accident, but I wanted to be there for her. When she was 4 months, her parents went ballistic. They told that she couldn't see me anymore and that she couldn't keep the baby. Every time I went to their house to see her, they would the cops and say I was tresping. I hated these people so much. I couldn't even be involved in the pregnancy because of them, and my parents wanted me to act as if my wife didn't exist. As if their grandchild didn't exist. Me and my wife ended up going to another state for a few days so we could married without their permission (I was 17 and she was 16). We thought now they would accept our relationship, but they didn't. They still kept us from each other. It was even harder after I graduated. I go to a college close to our city, so I saw her several times a week. Once our daughter was born, we both just absolutely adored her. Her mother brought in this woman from an adoption agency. I told I wasn't signing over my rights and she said that she didn't care and that I wasn't going to get to raise my daughter. I wanted to f***ing hit her. My wife was hysterical so security had to get everyone out of the room. Later that night, she called me and said that they had been pressuring her into adoption for months and she's afraid that they'll take the baby and that they sent her to live with her grandparents. I mean, they physically forced her into a car and drove her there (and their house was in the middle of nowhere). I went over there everyday. I was going to give them hell if they thought they were going to give our baby away. When my daughter was a week old, me and my FIL got into a fight in front of the house and the police were called. When they came my MIL, that b****, said that I was a stalker and that I d her daughter. I called that b**** every name in the book. It was the first I realized that no matter what, they were never going to accept me. I told the cops that they kidnapped my child and they were keeping her hostage in that house. Me and her got into this screaming match and the police told her that they couldn't keep my baby from me, so that b**** brought my daughter outside and said take it. It?! Really?! I called my wife, got directions to where she was and picked her up. Her grandfather tried to stop her from leaving but he's like 70 or some s*** so that ended quickly. Now the three of us live in my apartment (that was a month ago). Her mother calls, everyday saying that she will make her come home, me go to jail, and make her give up the baby. I just don't get it. We both go to school, we both work, we both take care of our child, so why are these people so f***ing evil. My wife doesn't turn 18 for two months, around graduation and we live about 45 miles from our evil parents so can they can they really make her go home?
