Opportunities provided by LBS MFin versus staying in the US

Hello WSO. Excuse the poor writing, I am rushing through this at work.

I am a 2021 grad who has been working in NYC within S&T at a low tier EU bank since graduation. About two months ago I left my job and started a new one last week at a BB, which so far seems extremely interesting, and I will be able to learn a lot while here, I am just not sure it will align with my long-term goals. During the last few years I have grown the urge to live in Europe and chose to apply to various Msc Finance programs across Europe. Last week, during my first week in this new role, I heard back from LBS MFin that I have been accepted to the 1-year program. Additionally, my girlfriend of just over 1 year lives in Switzerland while finished her Msc and we have been doing long distance for the last few months, so as a result this change would also facilitate the hours and traveling that we have done so far for this relationship. 

My main concern is the risk of paying full tuition with my savings and being unable to find a job. I have a strong resume with a good technical undergrad and both Sales and Trading experience over three years. I am curious if LBS will truly offer me the opportunities I seek in order to find a job. I wish to continue a career in markets but from the EU, so the risk of leaving a 175k+ comp job for a Mfin that will not allow me to get a good job and transfer to an industry that I love is scary.  

I have thought of the idea that I could accept the offer and continue trying to transfer internally or through the job market prior to the commencement of the master's program. I have flung the idea of pushing the program back by one year to give me time for scholarships, internal transfers, etc., but my girlfriend has really not been receptive to the idea, and it is extremely demotivating, since I would be happy there but exponentially more so with her by my side. I understand that it seems like I am chasing love, but I have been doing my best to be levelheaded, forget about her and speak with many people to get ideas and opinions, including WSO!

Please let me know of any advice or ideas.
