Hi, I'd really like to know how other people would feel in this situation. I have been with my partner for a few years. We both have children from previous relationships and we all get on well. We don't currently live together but plan to in the future. We both have good co-parenting relationships with our ex partners, which is obviously really good for the kids. My issue is that for his sons upcoming birthday he has agreed to go to a theme park for the day with his ex and the children and stay the night before in a hotel, in a family room! I have no problem with the day trip to the theme park, it's the hotel and staying in the same room that's really bothered me. I don't think there is anything going on between them but I find it really disrespectful to our relationship that he's doing this. He had a real issue saying no to anything his ex suggests/asks, which at times cause problems for us. He didn't discuss this with me before agreeing, which has also really upset me. He obviously doesn't have to ask my permission, but I would have a appreciated a conversation. He can't handle any sort of conflict so tends to just go along with things and I'm really struggling with this. How would other people feel if they were in my situation?
