Hello. I am hurt and confused and same time i wonder if he is right and it all happens because i am selfish and high maintenance as he claims
I am with DP for nearly two years.
Since i met him i always supported him with his issues. And he has many, real or perceived (in my opinion). He gets upset with work,with his landlord, his neighbor, with his boss, his family , money situations, it can be anything. He will always come and tell me about it, i think is a way to vent the stress. I will stay and listen to him hours at a time and he never seems appreciative. I dont expect thank you, i am happy to help but he will always turn and say that i do nothing for him or get upset if i offer a different perspective than his.
On the other hand i rarely bother him with my issues, it seems as he is having enough without mine. The last week many things happened in my life and i am a bit distressed. Today the car broke down and it will cost a lot of money to repair but i will have to because otherwise i can not work. I usually dont get upset over things like that but on top of everything else it just all got too much. I tried to talk to him just to get some emotional support (i guess i was expecting him for once to do what i do for him for two years now) but he seemed uninterested. He only told me that the mechanic is probably a scammer and how his aunt got ripped off by one . And that he is sorry .Then he started telling me about his work issues again.I told him that i am a bit depressed today but he seem so uninterested and he answered that he is not a woman and he can not reply the way i perceive right. Then he made a funny voice saying "i am so sorry" mimicking how a woman would respond and laughing. He said that is all in my head and he is a man and he will use logic to respond . And that i dont care about his problems and i project this to him and i think that he doesnt care either 
i know that i am emotional today , but is it too much to expect from him for once what i do for him constantly for two years?
