My partner of 8 year is away overseas for the long weekend for a work related trip. The company has given him and another college (woman) an allowance for the trip and so prior to the trip they decided that they would get a shared accommodation to save money. The accomodation has separate rooms which is fine and I was OK with this as I trust my partner but I told him that I'm fine with it as long as he is sure that if roles were reversed he would be happy with me staying with a male colleague. He decided that he would prefer me to stay in my own accom so he went to book a single room but by this stage the rooms had tripled in price so he is now staying in the shared accommodation. Since arriving, to get around they decided to rent a motorbike (one bike to share) to once again save money on taxi's. This makes me a little annoyed as I we spoke about our relationship boundaries before the trip and it feels like he is knowingly ignoring them. That was last night and I just sort of let it go but then today he has posting picture of him at his work event and one of the pictures is of his college sleeping (in a public place not bedroom) and this has just infuriated me. Isn't it weird he's taking pictures of her sleeping? Am I being unreasonable? I really don't believe he would cheat on me but it's more the fact that we have set boundaries for our relationship and I feel like he is crossing over all of them and making me feel super uncomfortable. Am I overreacting? Sometimes I honestly can't tell.
