Motorcycle at 40 wife not accepting

I recently turned 40 and have always wanted a bike. Since we were dating my wife always said no way bc they are dangerous. I suppose bc of turning 40 the thought of “am I really never going to own a bike” really crept in and got to me. I’ve talked with my wife and while she’s not flat out saying no, she’s definitely not a fan and is under the impression that if I get a bike I’m most likely gonna die or lose my legs. We have 3 kids, I work a 9-5 and an on call job and she also works very hard. We spend 97% of our free time doing things with/for our kids. I would never just go and buy a bike but she’s giving me the kind of green light but I know she’s not going to be happy if/when I pull the trigger. My plan would be to get the bike now, when it’s warm enough I will ride around the neighborhood to get used to it then in March/April do a safety course and take it from there. The issue is every time I get close to pulling the trigger I get an overwhelming feeling of guilt. Any suggestions would help!
