My two pen'oth is that you're husband is both right and wrong.
Dutch style bikes are only good if you're in an extremely flat place ... like the Netherlands. Pashleys in my view look great, but are heavy and are overpriced and a bit style over substance. I'd fight shy of an electric bike, simply because they are so bloody heavy and you're having to shift the bulk of the battery as well. Typically they are about 20kg, double what an entry level road bike would weigh and they cost ££££££
I think he's wrong that you need a road bike (I say this as someone who owns a road bike) and my first port of call would be to see if your current bike can be made comfortable. Trek make some very good bikes and it may just be that it needs to be adjusted.
Is the handlebar too low? For a hybrid, the saddle and handlebars should be roughly at the same height. Saddle should be set so there's still a small degree of bend in your knee when you are at the bottom of the pedal stroke. If you can touch the floor with both feet flat, the saddle is too low. Set your saddle height first and handlebar height accordingly.
If you feel a bit stretched out, try moving the saddle along the rails so it brings it closer to the bars. Also check the saddle is level it could be that it is tipping you forward. To do this, put a hardback book on the saddle and then a spirit level on it, adjust until level. You may also be able to adjust the stem and the rise of the handlebars depending on the model.
If that doesn't help, try changing the saddle (make sure it is woman specific model). This can be an expensive business as it trial and error, one saddle might suit one person won't suit another. Bontrager do offer a 30 degree refund if you don't like the saddle for whatever reason, so maybe try those first. Also a wide saddle isn't always the most comfy either. I'd also try padded shorts too.
If that doesn't do the trick, a good local bike shop might be worth visiting. If you explain the difficulties you're having and see what they'd suggest. If you haven't ridden your bike in a while, it could benefit from a service before you take it out again. They should make adjustments in set as part of the service or for a small extra payment.
Having said that, it could be that the bike could be the wrong size or have the wrong geometry for you, but I wouldn't be looking to buy something new without trial and error on your current bike.
