Your blog is all jumbled up so do I have this right? ...

Because your older spouces 30 year old son still lives at home your son and new baby all share a room with you and your spouse? 

But he made it seem like after you moved in he'd be moving out and now that's not happening? 

I'd be giving a date that adult SS needs to move out by or you're gonna be moving out with your two sons. 

His stepson?

I'm lost - can you clear up the formatting or re-post?  It's a blog, so you can edit it.  Sounds like your husband's 30-year-old son is still living with you, and now you and your young son and "ours" baby with BF have to sleep in the same room with you?

What does your BF say about kicking the 30 yo out?

How long has it been since you moved in?

Either your BF gives his son a deadline to move out, and sticks to it, or you go ahead and find yourself a place. The four of you having to share a bedroom is ridiculous.

My boyfriend SS still lives in the house... he is almost 30...

before I moved in I had plans of moving into my own place with my son (I'm younger then bf) but ended up moving in with my bf he made it seem like he was leaving but I guess not my son still sleeps in the room with us and now a month old baby... I'm honestly thinking about leaving... this wasn't apart of my "plan"...wth should I do
