I've lived with my girlfriend for two years. Both in our late thirties.

She is awesome, BUT at any given time she turns into a diffrent person.

This person is convinced that I don't want to be with her. So she accuses me of that. She then feels she isn't worth anything and that I must be talking to other girls who are more fun. I must be avoinding her etc.

When she snaps out of it, she can talk about it, and doesn't understand why she was thinking those things at all.

The trigger can be anything: I do'nt respond fast enough on what's app. I'm online on what's app and am not talking to her. We can have great conversations all day, but suddenly this all starts.

There is more to it then this but the constant accusations are really starting to annoy me. ( Yes two years will do that to ya)

Is it possible to give an ultimatum, or will this just feed in her fantasie?

Any guys out there who are also going crazy with this type of girlfriend?

My question: When she is in this "I hate myself mood". What can I do to break her pattern. How can I get her back??
