What should i do??

Well me and my bf are having disagreements about what we should do about my roomate and his son..
see the problem is that we found out about 2 weeks ago that he has a son none of us knew about but he was takin abway from his mother and now lives with his grandma but he stays with us durning the weekend and CPS called and said he cant stay with the grandma cause the mother has a chance of seeing the son and they dont want that but we dont have enough room for him cause i have a 3 bedroom house and our son,my bf,me and my roomate live there and theres not enough room for the boy so we were talking about our options and he thinks i should make me roomate leave but i dont think its fair cause she lived with me for 2 years and helps with everything i cant just tell her to leave cause we need to make room for his son and just kick her out like that she like my sister.

so what im trying to ask is what would you do if you were in my spot or what advice could you give me about this
i realy need some help on this one so please if you can give me some advice id REALLY BE THANKFUL

"...he thinks i should make me roomate leave but i dont think its fair cause she lived with me for 2 years and helps with everything i cant just tell her to leave cause we need to make room for his son..."

^ Then don't. Your boyfriend has no say in the matter, since, basically, he is a guest. You've lived with your roommate for 2yrs, that is a commitment.

Which son, the one you have together or the one he just found out he had?

Its not my son its his ans im not choosing my roomate over my boyfriend i just dont think my roomate should leave cuase he wants his son to leave with us and not the grandma.

we can afford it now cuase the CPS will help us but i dont think its right to just tell my roomate to leave so there will be more room and he dosent want any but family to live in my house..

He is living with the grandma right now but soon his going to have to move in with us cause CPS wont let her keep him i guess the mother of the boy has went by the house and shes not able to see him any more so we are thinking about taking him but the problem is he wants my roomate out and i dont want her to she my bestfriend and she moved with me when i moved to texas so she has no family to live with if i were to kick her out and i know im not going to anyways

and it dosent matter if we are married our not we still can take care of the baby and i bet im a better mother then some moms who are married but you can keep thinking all you want about having to be married i dont care

There was no lease or anything like that i let her move in with me when
she decided that she was going to the same collage as me and she needed a place to
stay cause both our families live in florida.

she gives me between $175- $180 a month
and that pays for everything.
i dont ask for much cause she helps me with the baby.

when she moved in with me she did know that i had my bf living with me also
and she was okay with that. Then came my baby and i told her she could leave
if she wanted to cause it would get a lil crazy with the baby coming but
she wanted to stay with me after all we grew up together and are bestfriends.

and now that my Bf moved back in she most likely will be paying only $150
cause he is going to be helping with everything..
but that depends to if her bf moves in after all or what they are
deciding to do about that.

but thanks for everyones help on this very stick subject and it did help me some
and im always taking advice from people

Glad to hear that you don't want her to move out and don't plan on telling her. Honestly, I think that was the right and fair decision to make. If you're boyfriend still doesn't fancy it, tough.
