So my boyfriend and I had a small issue last Wednesday. He initially told me he was feeling better but that he still misses his deceased cat. Before I go on I’m going to say that my boyfriend and I always joke around with eachother. So I told him in a joking manner “ I’m going to go out with friends and see what happens “ but then I said I was joking, and he got mad. 3 days happen and he texts me on his birthday which was on a Sunday, and he message’s me saying “ you acted like a asshole towards me, you knew I was going through a sad time, and you come and tell me something stupid , I’m sorry I know we joke around, but when you’re going through a hard time I talk to you, I treat you good, but I don’t tell you stupid shit like you do. I’m not breaking up with you I’m just telling you the truth. One more thing you don’t have to answer me today you can answer me next week or in two weeks , in a month or if you like next year “. I replied back an hour later when I filled down because I didn’t want to say something I was going to regret when I was getting kinda mad. Like I said I replied to him and told him in the message “ I didn’t know you were was still sad, you told me you were feeling better but that you were missing your cat still. I’m a human being I make mistakes I’m not perfect, but even if I made a mistake that doesn’t mean you have to come and tell me shit when I didn’t know if you were still sad or not. Like you said im not breaking up with you im just stating facts. I’m not perfect I make mistakes” and he just left me on read. I haven’t heard from him in 4 days, I don’t know what to do anymore.
