Feeling guilty about interview and looking to leave current role. WWYD?

[Maxine3477]

Ok so I've only been in current NHS role for a couple of months. I found it quickly as the other NHS service I was employed on before we closing down and I was facing possible redundancy. When I found this new job (the one I've been doing for a couple of months) I knew it would be a pain in terms of travel (out of the way location, no viable bus route, I don't drive yet and have to get taxis costing £30 a day).
The team I've been working on for the past couple of months are lovely, very small, close-knit team without any bitchy-ness, office gossip etc that you might find in other places. They've been so lovely and accommodating of me (letting my WFH a couple of days per week). However, they want me at the office more now as we've just had new phonelines installed and part of my role is to man the phones and great visitors etc.
Sooo.. as lovely as the team is, I've had to keep looking for something closer to home to avoid the expensive taxis. Buses aren't an option, would take me about 2 to 3 hours with several changes to get there by bus, too much messing about as I also have a young child to get to school in the mornings. I'm a single parent too.
Long story short... I've got in interview for another NHS job (locally to where I live) next week but haven't mentioned anything about this at work. I have a meeting with my manager next week (before the interview though) so I just feel a bit "sneaky" for plotting to leave when they've been so kind and wecolming to me, sending me on loads of helpful training, showing me the ropes of the job etc. Only for me to leave (if successful with the interview) after just a couple of months.
Obviously don't want to say anything unless I get the new job but, if i do, then how do I approach my manager and how can I explain my reasons? Feeling rubbish about the idea of just jumping ship when they've invested a lot of time and resource in me. AND they've been letting me WFH, but have made it clear that I'm expected in the office more going forwards because of the the new phonelines and visitors etc.
WWYD?

Cant you learn to drive? Move closer? Tell them travel is a problem for you and try to find a solution? Its very rare to find an employer as accommodating and supportive as yours appears to have been, plus an environment that isn't bitchy. Your future employer might be closer but not any nicer. I think you could have tried to resolve your situation instead of just quitting.

I started learning to drive before the first lockdown but the lessons keep being stopped because of the restrictions, then stopped altogether until after current lockdown. My driving has just ben stop start stop start, not getting far because lessons keep being put on hold. I wouldn't move closer to the office as it's not in a nice area, very isolated. I have a nice home and wouldn't give up that.

If you aren't prepared to move house either closer to your place of work, or to an area that gives you an easier commute to your work location, there's no point overthinking it. The fact is, you don't want to continue doing the journey, no matter how nice the people are.

Just be honest (if you get this other job), it's been lovely working with them but your family arrangements are such that you need to work closer to home for childcare and economic reasons and can you give me a fantastic reference please
