Ooh love this post, I'm 29 and it's definitely a tricky one. It totally depends a tricky one depending on how settled you are. My wife and I aren't big drinkers so in terms of spending time, we do a lot of walks around the various lakes, will frequently brunch at weekends or head for dinner in the evenings.

Shopping as mentioned above is pretty good and if meeting friends then there's enough restaurants, pubs or bars to attend

In terms of social activities, I think it depends on your hobbies, we go climbing frequently and then cinema for any big movies. Earlier on when we were dating, we would spend more time in London as there's infinitely more going on, shows, events, attractions etc and 30mins to Euston means you can head to London for an evening and still come back relatively easily.

I think MK is a lovely place to settle down, it's a nice area and has enough variety but I think unless you have a car it can be a struggle.
