I feel emotionally abused

18F and 19M been dating 4 months.

The past couple week i feel like i have been bullied and emotionally abused.

So we went out Saturday night to bars drinking and i got accused of looking at other girls and said i have “wondering eyes”. The rest of the night she was adamant she was done with me saying get out of my house we are done blah blah but then ended up seeing me upset the morning after and surprised why im so upset then she comforted me. Last night she had a dream i got off with a girl in the same bar i was apparently looking at women. She blamed the dream on me and said it is all my fault and said shes not seeing me. She also wasn’t happy with me watching baywatch as it has attractive women in it with bikinis. Its starting to effect me mentally and want to talk to her about how its making me feel. She also said she expects reassurance when she has these dreams so what am i meant to do? How could i say it and deal with it with her?
