How do I fix this?

Yesterday my husband and I were arguing over something petty so here’s a screenshot of the start of it

We’ve been together since were 14 now 20/21 and he currently lives away from me house hunting in the area where we’re hoping to move to together and I went out with my dad for dinner and a movie and he made a big deal about but he constantly buys stuff that he doesn’t need which I don’t care about bc ya know his money but it’s like god forbid if I spend $40 on movies which we go out once every 2 weeks just to have some fun either it be the movies or a walking trail or an arcade etc., as my dad recently got divorced and he had really bad depression so I like to get him out of the house to keep his mood up a bit! So anyways last night he says that I’m that the girl he fell in love with, haven’t been in 2 yrs(we’ve been through SO MUCH, but that’s a diff story) so anyways he says that if I can’t change back to her he doesn’t wanna be with me anymore that we’re just too broken and i asked how do we fix this and he said were just too broken to be fixed so I asked him so we’re done then? And he says no. WHAT AM I NOT UNDERSTANDING.can you guys give me some insight please. I do love him to pieces but I just don’t know if I can just go back to who I was. And I honestly didn’t know or realized that I’ve “changed”.ty all so much.
