I have my almost 2 yr old springer next to me, asleep (but with one eye open - if I move so will he!). He has only recently in the last few months started to settle in the evenings. Other than that we had pretty much no free time to ourselves. It is like having a toddler.
You have to puppy proof everything. He isn't our first working dog, but even our spaniel owning friends have said he's at the hyper end (one described him as having ADHD! he is non stop).
Going out for dinner as a family (we have two teens) is a birthday treat, because we can't leave him. It's inbuilt in him to be with his owner, to use his skills for what he's been bred for. If he's not physically exercising then it's brain games and enrichment to keep him occupied. We have had to teach him how to calm and settle, otherwise he won't switch off.
So if you're dead set on a springer, make sure you can commit to its needs, or you will have an unhappy dog, and lots of rescues already have unhappy dogs from owners that couldn't cope with their dog's needs.
I would recommend taking a "what breed for me?" quiz to find the dog that fits into your lifestyle. Oh, and no don't do it as a surprise, it's a possible 15 year emotional and physical commitment, not to mention associated vet fees. It needs careful consideration, from everyone.
