Hello, looking for outside opinions please. I've been seeing a guy for about 6 weeks now. It's going very well, but I'm very aware that it's very very new still. Anyway, it's my birthday on Friday. I mentioned it to him a week or so ago and he immediately said that we should go for dinner and to a hotel for the night, said that he would make arrangements etc. He sent me texts asking for info on what would make it perfect, the kind of place I'd like to go and said he'd take care of it all. I was very excited, because I really don't get out much (I haven't been away for the night in 15 years!) and it sounded like a really nice treat- I made arrangements for my sister to have my kids overnight etc.
Fast forward to a couple of days ago, and he casually mentioned he was thinking instead we should just spend the night at his flat instead as it will be cheaper. I'm not materialistic in the slightest and don't need a lot of expensive things to make me happy, but I can't help but be disappointed that he suggested a nice night out and a hotel and has now seemingly changed his mind about it. I didn't say anything to him and just agreed, but I'm a bit sad because I was looking forward to it. Am I being unreasonable? I'm worried if I mention it to him that I'll seem like I'm expecting him to be spending a fortune on me etc. In reality I wouldn't have even thought of it if he hadn't suggested it. I can't decide whether to bring it up or just deal with feeling disappointed, especially as it's such a new thing. I want to manage my expectations. I'm also toying with just booking a hotel myself, but I can't decide how I feel about that either.
Opinions? Thank you in advance.
