Did he said by accident that he love me ?

There is no way for me to know. I don't know anything about him or about your relationship.

Can you ask him?

Have you tried to get a relationship reading done ?

If you've been seeing each other for a while, then you should be able to have these sorts of conversations.

Yes. He told me yesterday afternoon when I was walking from the train to my home.

((To clarify... is your significant other a feral cat... living in Brooklyn? That's who I talked to yesterday afternoon... then again I could have projected my feelings about your relationship and the conversation could have been altogther imagined. I talk to that cat again today and hopefully verify or disprove my conversation ever properly happened))

G-
Shouldn’t you be more concerned that he’s saying that he has difficulty tolerating you?

He could have been teasing you - or was serious that its a good thing he feels like he does about you (cares for, likes, loves, whatever) because you take a lot of energy to have a relationship with.
