Life spiralling out of control....

Lost my job, found out I was pregnant(currently18w+5 and struggling to find work again), boyfriend lost his job, we lost our place, found somewhere willing to work with us on rent, paid 400 for 1 bedroom + lived on generator and paid for gas for that the whole month, got screwed over and kicked out, living with my ex in laws(I have sole custody of their grand kids, amazing people really even though they do have issues with us staying here(understandably) now while boyfriend is couch surfing and he lost his phone so we have very limited contact and everything just seems to keep getting worse! My boyfriend seems to have given up, he's a great guy usually, hard working, and loves to take care of me and my(our)kids, but ever since everything started spiraling, he seems to have reverted back into a teen who doesn't care about life(he's 25). I feel like things are over with us if he doesn't stop acting like nothing matters. I've talked to him multiple times and he keeps saying things will get better when we get back on our feet, but I don't see him trying much other than fixing up a house we could possibly stay in when its done(I'm grateful for the thought and effort, don't think im not) but he isn't looking for work at all anymore. What do you all think, I'm just hormonal(which i very much am) and wait it out and see if we can make it work through this life crisis, or just give up on this childish behavior he seems to be going though in our biggest time of need...
