Boyfriend wants me to put his car under my car insurance

Of course he’s kind and affectionate atm.
Lets see how he behaves when you refuse to fund his profligate lifestyle.

Seriously there is nothing to be gained from any relationship where one of the partners is bad with money.

First it's the insurance , then he'll come to you crying because he can't afford his rent and wants to live with you but he won't be able to afford bills ect. So you'll basically be subsidising not only him but his ex wife as kids. It has disaster written all over it

Alllll of the above.

If he's had insurance cancelled it's going to be a bloody nightmare anyway. They always ask if you have had, and lots refuse to insure if that's the case. The ones that do charge hugely for it. If he couldn't afford it before, he can't afford it now, no matter how much he promises you it.

Is your child/children in private school? His are, he's picking financially to do that. If you loan him money/put him on your insurance/buy food/pay his rent, you're also paying for that choice, when you're not making it for your own children. Every penny he takes (there will be lots of them coming up as well!) will be taking money direct from you and your own kids to fund his.
Honestly. Next will be the not paying rent, can I just stay with you/I'll pay towards food/it's just a few weeks. Do not under any circumstances say yes, he will drain you and never ever move out again. Your financial stability will go to shit and you and your own kids will suffer, you'll feel bad throwing him out as he will have nowhere to go, and you'll end up with a blended family where his kids get their own space paid for by him, but your kids don't.
if you don't want to ditch him fine, but keep it casual, with zero plans of living together/marriage until he's sorted his shit out. And don't believe the promises of he will once he's in your house. He needs to do it all before that.

he's suggested I put his car under my name so he can continue to drive it.

Well this is illegal for a start.

Don't get financially embroiled with him. He'll get you into debt is this really what you want for your child?

Nice, affectionate and not stingy? Well he needs to sort out his bills before he starts taking you out on dates and things. Don't be blind sided by love bombing have some sense run for the hills

Noooooooooo! He has an irresponsible pattern of behaviour. Keeping his car on the road should have been his priority, that means driving responsibility and paying his insurance. He rejected your CAB suggestion because he doesn’t want advice on changing, he just wants to carry on what he’s doing and have someone else carry the can.

If you did what he asked, he'd expect more and push your boundaries until your finances were shot. If you feel you can’t say no to this man, any man for that matter, then you shouldn’t be in a relationship with one.

This man is a walking red flag.

If he has had car insurance cancelled then your insurance company may refuse to add him to your insurance. With 12 points he sounds like a liability and premiums would be sky high to match his risk. He shouldn’t be expecting you to bail him out from his very poor decision making. I would refuse to entertain the idea and suggest he looks at public transport options in readiness for a driving ban.

Please don’t do this.

This sounds a lot like my ex husband, the financial issues will not get better. He hasn’t explained everything to you, so you don’t have the full picture. If you are going to become financially entangled with him, you need full transparency and you don’t have it. He’s obviously made some poor decisions along the way and seems to keep doing this -having so many speeding fines is a red flag. This is something he could have clearly avoided.

And please check for gambling issues. My ex had a gambling problem that got a lot worse once I was able to prop him up financially once we married. He was very good at hiding things, initially from shame, then from a sense of entitlement.

You are not responsible for fixing his financial problems. Or even making them easier. Support him in other ways-make him dinner, have cheaper nights out. But don’t get involved at a financial level. If he has an accident, this will affect your claims history and premium.

Put you and your child first and keep your finances separate.

There is supporting your other half to do better and be better, even financially sometimes and then there is being a sucker/martyr/desperate. It depends on situation.
Here you are about to fall into the second group....

You are just dating. He (and his kids) is not your financial responsibility nor are you his. Don't fall into the "carer" like so many women oddly keep doing

Keep him as a bf if you must but stay well out of anything to do with finances. He's in a mess, much of which seems to be of his own making, and he'll drag you down with him. I'm sure he does say he wants to marry you, given the next thing he'll tell you is that he's going to be homeless soon and can he move in with you for a few weeks while he gets himself sorted. Months later you'll be back saying he's costing you money as he's not found anywhere he can afford and he's not regularly contributing to bills. He has disaster written all over him.

As soon as I read “divorced with three kids” it felt like time to call it a day
you shouldn’t help because he’s looking for a place to live, someone to fund him, someone to sort his debt out
He will ruin your credit
if you do marry (of course he wants to) you won’t be able to afford to have children of your own because you’ll be so busy working to fund his other family

Because he's relying on you early on in a relationship.
Because he is clearly a terrible driver and has 12 points on his licence.
Because he shouldn't have children in private school if he can't afford car insurance or bills.
Because it's not your problem to fix and you'll never see that money again.
Because your name will be linked to dangerous driving and your own insurance premiums could they skyrocket.
Because he's shit with money and makes poor decisions.

Omg RUN

I would be telling him to go and talk to his ex about the finances. If he can't afford his rent, her rent, private school etc then they need to cut back

Keep well out of it OP

Run

Let him sort this out himself, you can't help him.
