Name of this drama/thriller movie concerning a female stalker neighbor

So I have been trying to find this movie forever.

I think its a Lifetime movie, definitely a drama or a thriller. It centers around a couple and their next-door neighbor I believe. The next-door neighbor is a (blond?) female posing as a nurse or medical assistant for the elderly or something, and she has her eye on the husband. I think there is a scene with a hot tub involving the neighbor and the husband, as well as a scene where the neighbor sneaks into the couple’s house pretending to be the husband’s wife while he’s wearing his sleeping mask in bed. At the end, the neighbor drugs the wife but doesn’t get away with whatever she’s planning to do – I don’t remember much more than that.
