unwanted houseguest

If it's just three days, I would suck it up. Take the apology (which might be difficult for him) for what it is, count the hours and wish them well. For the sake of three days (or 72 hours) you could seriously damage your relationship with your fiance if you take a heavy-handed approach at this stage. I think you should make it clear this has been a one-off though.

I empathise with you as I've been in a similar situation before...hope it all works out.

I would speak up. I know a few bipolar people working in healthcare and when properly managed they have never damaged someone's home. Maybe he isn't treating his bi-polar? Maybe you saying something will force him to find a better treatment, or even take accountability for his actions. He can't "blame" the bi-polar, he still controls his actions. And if you think your home or a people in it are in danger, maybe they should stay somewhere else.

Speaking as somebody with bipolar, he probably feels crap enough about it, and unless he's a douche, I doubt his apology was a result of him not finding somewhere to stay - he probably felt too embarrassed to apologise sooner or that the incident was too fresh. Turn the other cheek and just try to ignore it. If he's not had regular "incidents" , then it'll probably be fine.

I'm not sure what you mean by "incident" but provided he wasn't dangerous, and his bipolar is controlled, then I wouldn't sweat it too much.

Edit - just read that you're implying he was dangerous / destructive / violent. In which case, speak to your fiance calmly (don't mention that you don't care for the apology) and voice your concern about the safety of your home.

Emmy, that's a really hard topic and situation to give advice on. Bipolar individuals can be very unstable unless they are on medications not to mention dangerous. Your fiance should respect the fact that its your house and should resepct your wishes. If you are that uncomfortable about the situaton then asking the bipolar individual to leave would seem to be the best solution. However, if the bipolar individual is taking their medications and seems sincere about apologizing then you should at least consider listening but don't be afraid to set some grounds rules with consequences for not following the ground rules. Those rules need to be agreed upon by everyone including your fiance. It's really hard to have a perfect answer to dealing with such situations and I don't know that there is a perfect answer. Just don't be afraid to confront the situation head on and let your feelings be known. Hope this helps but they are just from experiences of my own and not professional advice. Good luck.

Hi!

First off, I can completely empathise with your situation. My ex was bipolar and used to have this level of incidents all the time, which is why I ended up leaving (smashed crockery, violence, trashed house) but I have other friends with bipolar who are nothing like that.

Firstly, I would hear the guy out, see what he has to say. Hear him out, it's a very complex disorder and takes a great deal of understanding. Then tell them you need some time to think, let them both sweat a bit and go talk it out with your fiance.
What you then need to think is a) do I feel safe with this person in my home? and b) are my family safe with this person in my home. If you cannot 100% say yes to either of the above, then they have to leave. Your fiance shouldn't pressure you either, you're not only thinking of yourself but of his 14 year old too. No one should have to tolerate that in their home, illness or not. He should understand that and yes, he may want to see his daughter but If you aren't comfortable with them staying remember it's your home too! Do try though, to put yourself in your fiances daughters and her fiances shoes, you only have to see him for another 3 days, They both have to live with the illness and believe me it is hard work! The guy probably feels terrible and just wants to make amends.
