do i even have a choice?

a few years ago, i left my job as a bank manager and moved down south. things didn't work out and i was forced to move back after a few months. when i came back, i called my job and asked if i could be reinstated as a part time teller. i didn't want all the stresses that came with the management position and i only wanted to work part time so i could be more involved with my family. they told me that a new position was being created that fit me perfectly and that it was a part time position. they were right, it was perfect, it required all of my expertise from the company and i did it very well and loved it! of course there are a few aspects that i don't love... and lots of stress, but i have a great boss and it really is a perfect fit.

a few months ago, my boss was promoted from VP to EVP and I knew something was going to happen to my job. Without getting into pages worth of details I'll just say a few years ago, he said if he got that promotion, he would be sure I moved with him. When he got it, he just said not to worry about it. Today, one of the girls from hr told me that a position will be created for a part time trainer. now i've been training tellers for almost my entire career at this company (including when i was a mgr) in addition to my regular duties because of my expertise on the system but this would allow me to just focus on training but one of my pet peeves about my current position is training BUT if i take it, i won't have to work saturdays anymore and i won't have to fill in at the branches when someone calls out. the reason i don't like training is that it interferes with my current position and duties. i used to love it but have grown to hate it because it's just in the way but if it was my only job, i could just focus on that. i told her i needed to speak with my boss & husband and would let her know by monday.

when i spoke to my boss, he basically said it would be better for me to take it which completely blew my mind. he's always been great to me, great reviews, great increases, great praise and always gets upset if someone from another dept asks for my help so you can imagine my shock when he told me it would be better for me to go. he said that he really needs someone full time in my position and i'm not willing to do that. he said he needs someone more willing to help out in the branches and i really don't want to be there so i understand his issue but now it seems as though i don't really have a choice. he basically said that he's keeping me on because he doesn't want to lose me and that's why it would be great to just transfer and that he desperately needs a full timer.

it's selfish of me to turn this down but i'm scared. i know how to train tellers, i don't know how to train anything else. i've always been in operations, since i started in banking. i think it would be good for me to learn a new realm and it would also give me a foot into HR which would be good in the long run. i was also pretty shocked when i told my closest work friend and her reaction made it clear she already knew (she's a higher position than me and is often privy to more).

overall, i think it would be good for me to move and there are a lot of benefits to me moving but i think my biggest set back is that i really don't have a choice and everyone made it seem like i did when in fact i'm going to end up losing my job if i don't go. it was like a big production to make me feel like my opinion mattered when in fact it doesn't and i think i'm just hurt.

it sounds so silly after writing it all out. it seems so obvious what to do. so why am i being so analytical and petty about it all?
