I am in a quite new relationship ( a few months) albeit have known this person a long time (around 5-6 years).
We've just spent a weekend together.
We planned the weekend, went out for the day on Saturday looking around a new city, and Sunday night we were just going to go to the pub near me for some drinks with a friend of mine. This is a pub I have a close connection to, I go in there on my way home from work, help organise events for them, I know most of the regulars and all the bar staff, she has been in there with me many times and always seemed happy there, has met most of my 'pub friends' and always had a good chat with them, all fine.
Sunday evening we were sitting watching TV and I said 'right, I will go and get myself ready' and she seemed surprised and asked 'for what?!' I reminded her that we were going to the pub to meet my friend.
She said she didn't know we were going and I reminded her that I had told her, but also said that if she didn't feel like it that was fine, I could cancel. She said it was okay and we both got ready and went. We got there around 9pm and the pub shuts at 1030pm, it wasn't going to be a long night(if relevant)!
When we got to the pub she was very quiet. I asked what she wanted to drink, she said she didn't want one. I was obviously surprised at this but tried to not make a big deal of it. Barman knows what she usually drinks and asked 'are you sure' and was also surprised, I asked if she wanted a soft drink instead, she said no.
My friend arrived and him and my girlfriend have a particular interest in 'real ales' and often spend time trying new ones and discussing them and he was telling her enthusiastically about the new one the pub had, and she barely grunted at him. He thinks a lot of her, we've spent time at events together and was very happy when we got together and was visibly confused.
I was half way through my glass of wine when I asked her if she wanted to leave, I could drive her straight back home if I didn't finish it, and she said no It's fine, to stay.
I was obviously worried about her and embarrassed but I didn't know what to do. At one point she took herself off in another room for a while, and then when she went to the loo my friend asked what was wrong with her, had we fallen out? I said no, nothing and I had no idea what was wrong.
I kept asking her if she was okay, had I done something wrong and she just shook her head and wouldn't speak to me.
We had two more drinks in total but, after I had finished my second one (she hadn't had one at all at this point) I went to the loo and when I came back she had bought herself one but not me. I felt that this must have really meant she was upset with me for some reason and we left shortly following. We were sitting at the bar and I was noticing the bar staff looking at me try to work out what was wrong.
We talked a little when we got home, and she said she'd felt like crying all day, was very down and didn't know why. She was upset that I cared more about other people than her (as I had mentioned people had noticed and were asking me what was wrong). This isn't true at all! But I did find her behaviour very odd, and if I am honest, rude. She left yesterday after asking me to take her for lunch, where we did discuss some things again and she said she just didn't understand 'pub etiquette' hence her not buying me a drink when she bought her own. I said I wasn't concerned really about that particular small thing overall, but it looks weird to bar staff and isn't a very nice thing to do to me.
I am not completely naive regarding depression. I have suffered myself, but I wouldn't ever behave like this. AIBU to be feeling like this? What would others have done in this situation?
