Been seeing someone for around 3 months. We get in we'll but he's quirky, which is fine - well I thought it was. Sometimes I'm starting to think he's just plain odd.
He's overweight and said he wanted to get fitter so I suggested he come along to my karate class. He did and I ended up mortified. He wore scruffy old jogging suit bottoms with paint on them and a massive baggy t-shirt with Harry Potter on. Whenever instructor showed him something he giggled. Instructor is hard arse, old school - I've known him for years and knew he was going to react badly. After 3 or so giggling moments and DB stood in weird positions and flapping his arms around like a little girl instructor said "what are you giggling at? Are you a girl or what? Do you have something wrong with you?". Everyone was looking. DB started stuttering and instructor carried on with "you know this is karate and not ballet don't you? Are you in the wrong class?". DBs face went bright red. I was mortified and just wanted to hide. Another female instructor said "alright, it's his first day" so instructor said "but what's he giggling at?". Anyway later on instructor came over to me and said "where the hell did you find him? Is he one of your patients or something?" I was so embarrassed I just said "he's a neighbour".
After the class I asked DB why he kept laughing. I'd warned him beforehand about the instructor. He replied "it was funny, I thought I looked silly!" So I said "you did, why did you act like that? It's a class full of martial artists, nobody else was acting like that" do he looked embarrassed and said "I don't know" so I said he shouldn't come again as instructor will have it in for him now. He got upset and said "but I like spending time with you" so I snapped and farted and said "well you embarrassed me, I've been going there for years and now I don't want to go back because of you, find your own hobby".
Anyway this isn't an isolated incident, a couple of weeks ago he embarrassed me in a cafe shouting and making a scene. In private we get on really well but in private he mortifies me.
He still wants to come to karate with me tonight. AIBU to tell him I don't want him there?
