I agree with a PP about driving. Neither of you drive? That stuns me. People should want to learn to drive, surely? Especially a male (have yet to meet a guy who actually doesn't want to get his licence). I am shocked at the attitude to driving on here that seems to represent mainly the UK. Where I am, driving is EXPECTED rite of passage/fact of life. Driver's ed is in school, and getting your licence is automatically as expected of you as it is that you will finish high school. Actually, more so tbh. If you don't want to drive/try for your learners at least, you are seen as if there is something very wrong with you. Getting your licence is like graduating high school, it's like wanting to get your own place. It's just part of life that you are automatically expected to do. Of course it's expensive, but, it is an expected part of life, just as finishing school/going to uni is expensive, moving out of home is expensive. But it is seen as something you are expected to do, have to do. So the cost doesn't seem to really be concentrated on just like the cost doesn't become the sole focus when going to uni or moving out of home. I just don't understand people not wanting to drive, it should be an automatic thing on graduating high school at the latest. So, with that said, if one of you at least, could drive, you wouldn't need to spend an entire weekend with your MIL. You could pop in for an hour or so, and go home. You wouldn't even need to stay for dinner. You are making it soo much harder for yourself than it need be.
That, is one of the many benefits of driving. You don't have to spend 3 hours getting somewhere that should only take one hour. AND, you can arrive/leave MIL whenever you want to! Because of this alone, you'd be mad not to get your licence. You are at a disadvantage in so many ways without it, and this, your OP post, shows exactly how.
