35m 32f - 1.5 month coming to end I think?

I get that 1.5 months is insignificant for many, and that I’m probably just in the honeymoon feelings, but I’m old and not good at this stuff…

Context: About two dates a week for the past 1.5 months, really enjoying our time together, she goes out for a friends birthday drinking and sends me some toxic texts saying “have a nice time with (co worker name), don’t talk to me any more, we’re done.” type stuff out of nowhere.

I get her on the phone and she tells me that she just ‘felt like being toxic’ because she was bored, after I told her to grow up she tells me that she doesn’t think she sees herself in a relationship with me because ‘we’re too similar and I hate myself too much to be with someone similar to me’

Cut my losses, or what
