Just been speaking to a friend and she reckons this is what is going on here. it hadnt occured to me before!
So basically boyfriend is in the process of selling his house. He is living with his mother until he finds somewhere else to buy. He is struggling with this as he says he doesn't want to buy anywhere when there is a possibility we might move in together next year - therefore he feels he should wait and then we buy somewhere together next year.
In the meantime however he keeps saying how much he hates living with his mother (as lovely as she is) and he doesn't know if he can hack it there much longer. He's said this a few times now - like he'll say "oh, don't know how much longer I can stay there, it's doing my head in but I don't know what to do about buying somewhere else ... " and then he seems to wait for a reaction from me and when he doesn't get one, he changes the subject.
Now it's far too early for us to be entering into a commitment of actually buying somewhere together but my friend thinks he see's moving into my house as a stepping stone solution. He's not tied here if it all goes wrong, we can split easier without any messy property to sort out and if it all gets too much, he can go back to his mums.
Is this what he's hinting at?? or are we reading too much into it?
