When a guy says "Yeah we straight?

So we've been talking a couple months he's going through some personal stuff. I told him I was here , if he needed a place to stay etc. He told me he needed to think about about everything first and to give him some time. I asked him if we were good and okay and all he said was yeah we straight. What does that mean? Last time I asked him he said we were good.. now he said that.
