<human>: Just to clarify a few points: My boyf lives in the same country, but about 4-5 hours away by train. I am NOT considering cheating, or breaking up with my boyfriend. 

Having said that: for the past 4 months or so, I have had a seriously overwhelming desire to make a move on one of my housemates. So far, we have done nothing *too* inappropriate- we stay up late talking about emotional things; our dreams, ambitions, and insecurities, and once we shared a prolonged hug.

I communicate frequently and effectively with my boyfriend, and have explained my feelings to him. We used to be poly (I had a gf, but it didn't work out) but my boyfriend has never been ok with me seeing other guys, because he feels threatened by it.

I tried overcoming the crush/infatuation in various ways; I tried avoiding my housemate, then tried considering all the things I dislike about him, I wrote pro and con lists, I re-evaluated my devotion to my boyfriend, I hugged him and got close in that hope that that would be enough... but nothing seems to work. I absolutely WILL NOT cheat or break up with my partner, so I felt like there was no solution.

Tonight, my boyfriend and I negotiated further and he said he would give "real poly" a chance. He said that I could "see where it goes" with my housemate, as long as I remain in open communication about what happens, and that I will call things off if the bf decides this is too uncomfortable. Also he requested that we absolutely must call it quits when the housemate moves out in six months (this is also when my boyfriend moves to my city, so I feel it will be easy to quit then).

Given all these caveats: is this a bad idea? Or should I stop overthinking it and see what happens?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My boyf gave me the go-ahead to make a move on my male housemate. I really really want to, and I know the housemate does too... But should I?
