How can I breakup without being a bad person
So guyss before judging me listen the whole context the me and my bf (18) is being in a healthy relationship but the thing is he is emotionally insensitive like he usually do trauma dumping like how his parents is mistreating him and all and like a good and caring partner I always support him and this is what I expect from his side too like when I have some family issues nd I talk to him he usually took that lightly and many times laugh about it and joke about it and that's the case like things that are light and funny for him is not a joke to me like I am currently depressed about my merit and colleges nd he usually joke about how my cousin got more marks than me now this pattern are continuing and every time I confront he always says he will learn from it and he is trying but now I am fed up and wants to break up but he is not letting me go always promising he will be better but being a soft hearted person I don't know how to ask for breakup like I don't want to be a bad person
For more context at first we talk for hours but now we can't continue our convo for even half an hour
So pls suggest some ideas to breakup
