Date ideas in the winter

Now that it’s getting colder and colder out it’s getting hard for me and my boyfriend to go on dates.

In the summer we would do picnics and go to parks for hours and just chill there. Now it gets dark so early and we don’t have as many options.

We usually just do the movies, the mall, mini golfing or this arcade/bowling place.

I just don’t want him to get bored of the stuff we do.

Anyone have any ideas of what we can do?

We also go out to eat pretty much every date and I’m gaining weight

Btw we both live with our parents. If we didn’t, I’d have a date night in or romantic cuddling and movie watching but we unfortunately do not have the luxury.
