Tacking this on to your latest post in the hope you see it.

Obviously you're in a shitty situation at the moment. You need to find a way out of it. There are a lot of posts here saying that you should cut off your boyfriend and family and move on with your life. From the sounds of it, you've gone a fair way down that path already.

I'm going to take this opportunity to suggest that whilst the situation with your family sounds frankly terrifying, all (that I know) your boyfriend has done is be an idiot and ask your dad whether he can marry you.

Clearly that's not a particularly tactful thing to do, and you can see what Reddit thinks of that and come to your own decision on what you think of it. If you decide that, yes he fucked up but you'll be able to forgive him, then depending on the feel of your relationship (which I have no idea about) you can probably (or not) depend on his help at this point in your life.

Give him a chance to fix his fuckup and prove to you that he's worthy of being your partner.

Nobody wants to be homeless and penniless, and it's absolutely not too late to get yourself out of this mess.

Contact him. Explain to him what has happened (for all I know he thought your dad had talked to you or whatever before he realised that wasn't what you wanted) but be gentle. He was expecting to marry you and now he's hurt because he feels like a fool. You mentioned in the top post that marriage wasn't completely off the table, just that you aren't prepared for it at the moment. Clearly you do love him (or did anyway).

You want to bring it to his attention that you are his partner. You need to explain to him that what he did was stupid, and that he should have asked you first. You need to tell him that your family situation is completely fucked. And you need to ask him if he's willing to help.

At the same time you need to try not to blow up what remains of your relationship with him. This is crisis management, not an argument. Be calm, be assertive, and be understanding.

Reddit has already convinced you to torpedo your relationships once, you need to take a step back and try to salvage what is worth salvaging. Above all you need to retake control of your life, and from the sounds of it, the best way is to break away from your family for the moment and get whatever help you can.
