<human>: I'm a 26 year old Male. I'm friends with both of them. I've known him for almost 5 years now, and I've known her for about 1 (our group of friends used to hang out with hers). They dated for a few months before deciding to move in together (complicated but it made sense). They've been living together for about 6 months now. Today I saw on Facebook that he made a post asking if anyone knows of a 1 bedroom apartment for sale in the area because he is looking for one.

Obviously, I'm not sure what to do, if anything. I think it's pretty clear this means something is wrong with their relationship (he's complained about tension the past couple months, but he never made it seem really serious), but I don't think it's really my place to ask directly. I was thinking of inviting him out to a local bar we hang out at with another friend of ours, but I don't know if that is making it too obvious. Maybe I should just do nothing unless he brings it up. I'm closer to him then her, but I'm not really on either "side."

Give me a shortened version of the text
