I think that would depend on the ex and the current beau, prhoshay. I wouldn't care if my ex lived across the street and house sat and all of that good stuff. We were good friends first and stayed friends afterwards for awhile. My husband, however, would not be comfortable at all. And I really can't say that I'd be comfortable with any of his exes. I know that there is nothing left with the ex, but my husband doesn't know that for sure despite how much he trusts me. I'm jealous of Rattus and her relationships!
