I am so beyond devastated (long)

When I was 19 I was living with some not so nice people and dating a guy who was bad news. A girl I worked with and I became really close and she talked to her parents without my knowledge and begged them to let me stay with them. Her mom said yes and even though they didn't want my boyfriend there they allowed him in as well. Three months go by and I found out I was pregnant. My boyfriend had gotten pretty physical with me not long before I found out and I ended our relationship. This family stuck by me through the pregnancy and all. When she was 8 months old I found out that they were getting foreclosed on and I found them a rental and helped them figure out how to go about it all since they weren't sure how too since they are older (65) and not up to-date with things. Well we moved and they continueously said I was like a daughter to them and my daughter calles them Nana and Papa they intergrated me into their family. When my daughter was 1.5 I met a man. We got married a year later and the way things went we couldn't afford to live on our own and they said they would love for us to stay be a part of the family. So we did. And we didn't just live with them and do nothing I cleaned and cooked and helped get the bills paid on time since Karen has MS and other health issues she can't really do it herself. I made myself useful. Last month we found out the home owner wanted to move back in and we were being evicted. Still my husband can't catch a break with a descent paying job and we can't afford to live alone. We found a larger cheaper home we all agreed on we have been here a week and David blurts out they are moving in August. And they are done. I am so lost. I call them mom and dad. They know our finances and also understand my daughter will have no where to go but foster care if we can't provide for her or worse her abusive bio father. And they just dump this on us. After telling me for so long how much they love me and see me as a daughter and her a grand daughter I just don't understand. My friend is so angry she won't even look at her father much less speak to him. And on top of all of this I am 10 weeks pregnant. Something we couldn't avoid. We tried every birth control possible and my body rejected everything. I am just so hurt and I know they owe us nothing and have done a lot for us but to just say they are leaving and sticking is with a rent payment plus utilities that they know we absolutely can not take on no matter how we look at it. Baffles me how they could ever claim to see me as a daughter. How would you handle this? I mean at one point they even considered adopting me until I got married.

Now the reason they are doing this is because of a comment I made which I apologized for when I realized I hurt her feelings towards Karen (mom) that mind you her own daughter has said before and she shrugged it off like it was nothing. I passively called her senile because she can't remember things all the time and as I said her daughter has said the exact same thing and she didn't bat an eye lash. I just don't get it.
