advice needed

Hello everybody,
I was leading a quiet and peaceful life in Tenerife until a few months ago when I met a lovely Polish lady, and we are in love now.
I am a British public health specialist, personal development coach, and have published a number of books (personal development and psychology).

My girlfriend, has a prominent executive job with high income, but the job occupies most her life, and some times leaves her exhausted. She is actively thinking of leaving that job behind, and living a simpler life and spending more time together. But this cant happen overnight, and I cant let her throw her career away just like that because we have fallen in love.
I currently work mainly as a writer, and my life allows me to spend a few weeks in Warsaw, and come back to Tenerife when I miss good weather.

I, however, need to keep myself busy with some work, friends, and social network, not to feel too isolated.
I dont speak any Polish but speak English, Spanish, and French. I wonder whether I can find a job there to keep me busy and active over during the time I am in Warsaw. I may need to spend the larger part of the year in Warsaw for next couple of years until we find a solution to my girl friend´s work situation.
Any advice deeply appreciated
