Was this situation inappropriate?

I think she is silly.

I think the older brother, instead of spending the weekend with you, should've asked you to come and spend the weekend with him and his wife, and family, while your husband was out-of-town:
1). You would still have 'company' for the weekend
2). The older brother wouldn't have been away from HIS wife & kids
3). There would be no appearance of impropriety
4). Your sister would have no basis to bitch

Unless you omitted some important details, your sister's characterization of the weekend with your husbands brother as: "incredibly inappropriate" is completely unjustified.

Nope, she's being crazy. It sounds like your husband trusts you & wants you to feel safe, you slept in separate spaces & nothing inappropriate happened. You did nothing wrong.

You might want to look into getting some treatment for your phobia though. It doesn't effect you right now because of your living situation, but (God forbid) your husband get sick or injured or passes away, the fact that you are not capable of staying alone could make a traumatic situation like that much worse. It usn't a healthy phobia to have & there is treatment for anxieties like this.

The fact that she's spilling her dislike of men on you isn't normal. Ignore her. Your husband wanted you to feel safe and there's nothing wrong with that. You might want to seek help for your fear though.

It really depends on if your husband's brother was actually trustworthy or not. in a 1000% decent world it would be fine, but this world is not really that decent.

Unless their brother started sleeping with you, it's fine.

Your sister is a manhating weirdo.

Your sister is a nutcase.

Well, nothing bad happened, so I don't understand why she's being so weird about it. She probably has nothing better to do with herself.

She's sexist probably or from the sound of it with another male bit sounds wrong

I think it depends on what type of person your brother-in-law is. I also think that it would be rather neglectful of his own wife, and children to be spending the weekend sleeping on your couch, just because you're scared of being alone. I think you ought to get a big dog for protection if you're that scared to be completely honest.

I don't understand what is with the trend of women living by themselves is all about. You were born in this world alone and then you learn to live alone. This situation isn't necessarily inappropriate but more awkward. Distinguish the two.

yes

I'm a very distrusting person and tbh it sounds a bit strange to me that your hubby didnt want you to go to his brothers house with his wife there. But like I say om very distrusting of people.

Your husband knew how you felt and wanted to make sure you were ok.. there is nothing wrong with that.. unless the brother had done something to you then thatll be a different story

I think it was an overreaction to need a bodyguard but I don't think you, your husband or his brother did anything wrong here.

Your hubby trusts his brother. Since nothing happened, who cares?

I think this sounds lovely of him. I think you should stick to your original thoughts. Clearly, your husband and his brother care about you enough to take time and inconvenience themselves to make this arrangement. So long as he discussed it with you prior to doing it, and you had a choice to say no then, frankly, I would be annoyed at your sister for bad-mouthing your husband on this one.

I'm not saying this is the case; I'm just trying to grasp why she would say this, but have you ever felt that your sister is unhappy with her relationships with men, or is jealous of you for the nice family unit you have?
