Thank you Starling for having looked up some websites on my behalf.
I do have quite a few friends, both M and F (she says, defensively!) but my quest was to find a poss potential housemate. It's not the friendships I;m lacking but I don't like living on my own and want the security/companionship of a like-minded person to share the/a house on a long term basis. I have house-shared with various F's over the years and generally got on well and they are still friends, but on a more permanent basis thought a M would suit better. Can't quite explain why.
It's a difficult one. Not looking for a friend, not looking for a boyfriend, but a housemate. I know there are sites like Spareroom.com etc but they all seem a bit transient and non-permanent - maybe I will give them a go though & see what replies I get, if any. Sorry long reply!
