Could it be that I really didn't know my boyfriend for all those years?

Broke up with boyfriend of 7 years. I stayed calm and just told him I couldn’t see a future because he won’t change and I can’t expect him to. He has some challenges being straightforward about certain things. I wished him the best. He asked if I met someone and I said no which is true. He then started saying he will meet someone else and that person will be inclusive as opposed to me which is the opposite. I have no friends according to him but he has a lot of really long time friends however he grew up in this area and I did it. And the fact is I do have a few friends but not many since I work full-time and raise to family. I kept the conversation low-key as best as possible but he was obviously upset which I understand. He said he needs to tell his family and friends and he’s concerned but since I don’t have any friends I just need to tell my 2 sisters. He further said it will just be me and my two kids and I won’t have anyone else in my life and furthermore I’ll never find another man to love me as much nor will I find a man at my age to be willing to undertake the baggage I have according to him which I assume means my son who has mild autism and I don’t know what else he was referring to. I am financially independent and I’m very social and generous. Finally he said the least I could have done is have sex with him before I broke up. It's hard for me to believe this is the same person I've been with for 7 years that I once loved.

Ignore him, he's lashing out saying shitty things cos he's angry that you ended it. You did the right thing. He sounds like a sore loser.
