Hi OP. I know it must be difficult for you to worry for your daughters future, and feeling she is making a mistake, but it is her choice.
She’s not listening to you because she knows you’re not supporting her decision right now. You need to embrace it, and listen to her side. Be emotionally supportive right now. The fact that she’s researching parenting and studying is a good sign.
Once you’ve opened up a good line of communication, it will be easier to explain some of the challenges she will face, and give her the opportunity to talk through all her options and how it could work. Rather than say ‘you won’t be able to do x once you have a baby’ try asking ‘have you figured out how x will work with a baby’. Allow her to come to you to talk through everything.
It’s really kind of you to say you won’t be kicking her out. You’re clearly a great mum, so have confidence that she will be too.
In respect of the bf. It’s clear he won’t be that involved, but when baby arrives he may feel differently and offer some support. Have faith! No, he can’t financially support her right now, but there’s plenty of financial support out there for young mums.
It’s a shame she won’t get to go out partying, and you can make it clear that she will miss this. Does she go out with friends lots? Festivals, clubs, spontaneous nights out are all gone. But I think that comes as a shock to new mums of any age!
You don’t have to provide financial support or babysitting services to be there for her. Emotional support is key here, whilst still keeping boundaries about what help you can provide. It will empower her to achieve and keep a good bond between you, which is so important. Make it clear what support you can offer. She’s not a child anymore, and I know plenty of people who had children young and are amazing parents.
Wishing you all well and I hope it works out for her, whatever she decides.
