Ross'a fling with his student

I recall years ago Ross had a fling with a law student , while being married to Blake. It really shocked me considering Ross always came across as a loyal partner. At least I don’t recall him ever cheating with past paramours. Anyhow does anyone recall the name of the young lady. I do recall she was little off, since she fell for Ross since he resembled her deceased bf or husband. Does anyone recall how Blake handled the messy situation?
