Should I be okay with my boyfriend moving in with another girl?

My boyfriend is living with his friend right now. He wants to get an apartment with his friends, but they don't have jobs right now so he doesn't think they would be able to get an apartment.

His female friend wanted to move in with her boyfriend, but her boyfriend can't afford to move in with her right now.

She suggested to my boyfriend that they should move in together since they both want an apartment. I am not okay or feel comfortable with this. Any comments, opinions or suggestions will be appreciated.

P.S My boyfriend used to have feelings about this girl, but claims that he does not have feeling about her anymore because it was a long time ago...What should I do?
