My (28) boyfriend (34) is obsessed with the fact I went to a psychic/medium.

So, my BF has been going through a tough time, having recently lost his mum to a terminal illness after a two year battle. I have made a lot of effort to be supportive and help him through it and he has been doing a lot to help himself too, such as going to therapy, meditation and doing things he can to keep himself occupied.<br><br>A few days ago I texted my BF a meme, it was a photo of a haunted house from the movie The Conjuring, with the caption "When you give a psychic your mum's name and she doesn't say the name of your girlfriend". I thought it was pretty funny but I knew that my BF wouldn't find it funny. He thought it was really insensitive and rude to make a joke like that when he is grieving his mum and I agreed, that it was an insensitive thing to do. I thought this was the end of the argument, but unfortunately it wasn't. <br><br>He then went on to ask me if I have actually been to a psychic and I accused him of trying to create a random argument out of nothing and answered "why would I go to a psychic?". He then went on to tell me he found out through one of my friends that I went to a psychic when I was a teenager, and that he has a problem with it, because psychics prey on vulnerable people and give them false hope, and he would have hoped that I would have "grown out of it". <br><br>I responded by telling him that it was over 10 years ago and I was just a naive child, and it didn't mean anything. I also went on to tell him that I have never believed in psychics, and I have always been skeptical of them, it was just something I did because my friends were doing it and I was young. I also went on to explain that it isn't a big deal and he shouldn't be making such a big deal out of it. <br><br>He said he just has a strong opinion on the matter and that it is disrespectful because his mother would not want false hope and that in his eyes it is disrespectful for me to even consider that type of thing. He also said that he hopes I am not planning on pursuing anything like that in the future or considering other things like that. I told him I wasn't, and that I think he has overreacted and gone too far by trying to dictate what I can and can't do. <br><br>We are still arguing about this, almost a week now. I think he is being ridiculous and going too far with the issue, and he thinks I'm invalidating his feelings about his mother. I'm starting to get a little worried that he is going to want to break up with me because of this and I don't want that. I want to know what to do because I'm not sure what to say to him anymore.<br><br>EDIT: I emphasise that I do not believe in psychics, I just went when I was a teenager out of curiosity, and I am skeptical about that kind of thing. I have not gone since I was 16. I also have never told him I was going to go to a psychic or medium after his mum passed away so I don't see why it would offend him. I have never mentioned doing such a thing.<br><br>EDIT 2: For everyone saying I'm invalidating his feelings, that's not what this is, he is the one that is invalidating MY feelings. He is saying that I am "disrespectful" and "immature". I think it is completely reasonable to stand up for myself when he is making those accusations. I have been nothing but respectful towards him and his feelings, and he has been nothing but accusatory and dismissive of mine. I understand he is grieving and has every right to be upset, but that doesn't give him an excuse to be abusive.
