AIBU to live with a cheater

[prawnsword]

Am mid 30s, housemate is mid-20s
Said housemate was freshly single when I moved in
They occasionally cry & call ex to profess their undying love/lament over this lost love (usually after a few too many drinks every week or so)
Since living here there has been literally countless people in & out, usually tinder dates. Our house has been a revolving door. One of them even thieved from us while we were asleep !
During this revolving door one person in particular was here quite a bit, in between the others.
Housemate is now going steady with this person & has confessed that they have promised they aren’t seeing anyone else
The thing is they still are - there have been two others here this week already & it’s only Wednesday! Also they tell me they still are very much in love with ex & can’t see it changing anytime soon
I often overhear them future faking to the current steady partner - eg “wow i can’t believe you do X that is such wife material” and going on holidays to meet her family etc.

It’s becoming a bit difficult to not think less of my housemate about this. I would move or except am currently piss poor & can’t move for at least 6-12 months.

AIBU to secretly judge ?

I have started hiding my luxuries like nice extra virgin olive oil & chocolate from them now. I have realised they never replace them but enjoy taking !

Of course it's not unreasonable to secretly judge, every person alive does this to some extent. Where it becomes unreasonable is where you start trying to get involved.

In terms of lots of different people coming and going, I'd not be so happy about that if things are going missing etc. When their personal relationships start to cause a problem in your life is when it's ok to move from secretly judging to actively kicking off.

Unfortunately, it's just one of those things you have to tolerate when house-sharing. Do you have a lock on your room? Keep nice things in there. Yes, it's a pain, but just part of the deal with there are lots of strangers in and out of your house.

Or could you ask housemate to conduct rendezvous at their homes, not always yours? I think fair enough if you've been burgled as a result!

The rendezvouzes (zi?) always seem to be here... except with the steady gf there are sleepovers there.

No locks on doors here unfortunately, but have found some new spots to stash stuff now!

Never lived with such a prolific cheater...
