If you have 30 days to make up your mind, why not go to the bike store and try their other bikes too? It's usually not the best idea to have someone else pick a bike for you.
That's a cute cruiser/comfort bike and it's fine for flat riding just to the corner store, etc, but if you want to put in more miles and meaningful regular exercise, it might be too heavy and not have enough gears to get you riding a lot.

I can envision you on a women's hybrid bike- it would be able to do all kinds of riding and you wouldn't outgrow it as fast when/if you start riding more. Hybrids are quite comfortable as well, but more versatile than this comfort cruiser.
That puffy saddle might get painful on rides over 5 miles. Hard to believe, but less padding is actually more comfortable if you're sitting on it for more than an hour.
Very sweet of your BF to do that for you.
Go to the LBS with your BF and try out some of the OTHER bikes there- especially the 'hybrids' I'd say.

On the other hand- if you are happy with short trips around town and no hills to speak of, then this might be just the right bike for you to enjoy.
