Mother in law lied to me

Long story! My BD and I had a lot of reckless fun. So much fun to cut loose with a toxic sociopath, until it isn’t. So, I reel it in when baby is born and, to my surprise, he does not. He’s on a motorcycle with a cigarette doing a wheelie on the way to the skatepark/tattoo shop where he’ll consume endless caffeine and nicotine maybe some weed, beers or mushrooms. Who knows, life is a box of chocolates! No problem! I’ve got the baby. Then he starts to resent my…. Safety concerns? He wants to drive the car with the baby outside his car seat, he wants to skate holding the baby, he wants to take the baby on a motorcycle across the country. Stuff that is always beyond a line of almost anyone’s reason. But hey, that’s what I’m here for, reeling it in, no problem. I’m thrust into position of supervisor because this dude just REFUSES to use careful judgement. Then comes a little neglect on his end, here and there, leave some buckles unbuckled, go outside and smoke while he’s on duty while I’m in the bathroom, moping if I leave him w baby for short periods cause he’s “not a baby guy”. Then relationship turmoil begins. He resents how mommish and uncool I am. Then comes the wanting to die. The endless unhappiness living under my unending gaze. “Thats not safe” he likes to say to mock me whenever I make a mistake (which are still relatively safe as I am not skateboarding or climbing a ladder with my infant). We split up. Finally. Great, the toxic fear of abandonment and his want to continue to use my home and property keep us intermittently and hesitantly trying to make amends but I’m done with sex (because this man has become a child and I’m not a pedophile) so he is horribly hostile and thinks he’ll win me over with cruel manipulation over kind words (which he has become incapable of speaking). I fear my child to be alone with him. I honestly fear for his life. Not due to intentional violence but due to the reckless abandon that a suicidal sociopath clings to even while holding his infant child to remain SUPER COOL, nonchalant, not a problem, so fun, ommmggg can’t believe I get to know this super fun man. His mother agrees to watch her son watch my baby on Sundays. First it was a few hours and by now it’s 10:30-7:30. He also drops in at my place whenever he feels like it, but that’s beside the point. His mother and I….I thought she was on my side about something specific (which duh, of course, why the hell would she be on my side). She agrees he needs a little supervision. She gets it, he’s just “not a mom”. He doesn’t know the schedule or the diet but, you know, that’s my problem, he’s the fun guy. She tells me she’ll watch. She’ll be my supervisor. I only gave her one rule with my baby, my world. No vehicles with daddy. No moped, no 1983 Porsche 944, no 1979 volkswagen transporter van, no 1988 ford f150, no motorcycle, no bagger, no dirt bike. This man has a driving record that is endless. The tickets have not altered his driving habits since he was 15. He stops at a red light, but only for moment. He doesn’t care about any laws. None. He is a reckless maniac limited only by the horsepower available at his budget. Today! My lovely Sunday off, I go shopping w a friend and as I drive home, from the direction of the skatepark I see this man, with my baby in the front seat of his truck (in a rear facing car seat). He doesn’t see me. I make a uturn and go to his house, he’s removing the baby from the truck as I pull up. I ask what’s going on. His sister gets out of the car. She smiles and waves. Then she realizes I’m super uncool. I somehow converse with him calmly as, at first he lies to my face, and then switches immediately to accusations about being controlling and how he doesn’t like my car (my car with crumple zones, designs in an era dedicated to safety, again, so uncool). I am so heartbroken. Anticlimactic ending. His mother promised me aggressively and repeatedly, the baby doesn’t go in those cars. He may go on her car, or her husbands car, with someone. But no. She let him do the only thing I put my foot down about, and I doubt it was the first time. We have court to prove paternity on the 8th of October so I think while I’m still the only legal guardian and supervisor I can trust, we’ll wait until the court orders me to risk his well-being. Today all I could think is, I’d like to call CPS on myself for being so gullible and beleiving these 2 can be reasoned with. This man uses forged insurance cards to get out of tickets. He has run from the police with me on his bike. He has left the scene of accidents, he has dropped tires and dirt bikes he failed to strap down off the back of his van. I have seen him strap the car seat down with the shoulder strap only. I have seen his do 1/3rd of the baby’s buckle. I feel lm…. Losing my mind. I don’t even know what kind of comments will help me. Someone please, if you read this and know a good custody lawyer in Chicagoland, send me their number.
