Just agree with her and tell her you're right, my kids will not sleep on the floor, until your new place is furnished adequately for the children, bring them here, they will sleep here until you can provide beds for them.
I would not have told her you love her.
Telling her that she is on her own because that is what she wanted and that she'll have to figure out was good, just make sure you're not being too punitive towards her about it. Just matter of fact, you've accepted everything that has happened type attitude and that she should too because this is what she wanted. Don't rescue her, don't offer to, and expect her to be angry, expect the temper tantrums, her fantasy world is colliding with reality and it's going to be messy. Since you know this, since you know she's going to get angry, there is no use in you getting trapped in that same situation, you don't have to argue with her, you don't have to get emotional about any of this. When she starts going batshitcrazy on you, you tell her "look if you expect me to reward this crap behavior of yours with my attention, you're sadly mistaken", smile at her, turn your back on her and walk away and don't give her another moment of your time and do this regularly, let her learn that you won't reward her behavior with your attention, don't just say it, mean it, show the action behind the statement - it sounds like she's experienced at yelling at you and the cursing,etc. Stand up for yourself, you're allowed, you're not just a man, you're a human being, how would you feel if you watched someone else get treated like that?
As for her text, don't respond, it's not necessary.
Her wanting to be friends after cursing at you like that, is just more words, it doesn't mean anything. When she acts like a friend, then she can be one, until then, she is just... "herself" for lack of a better title or description. How many of your friends disrespect you like that? Probably none except for her, I wouldn't be friends with anyone who treated me like that, but then again, that's just me.
btw - your user name is so depressing, why "crushed2death", you're still alive, you're fine, you're great, you should be "woken_up_and_feeling_great" or something positive, that other user name just resonates bad feelings and you're better than that, just my 0.02 cents.
