Does anybody have any date ideas?

We have been dating for about 2 months. Ive kinda run out of ideas. Last week we just watched movies at my house which i like doing but i just dont want her to get bored. We are both in college and live with our parents. We have been hiking and shopping and to the water park. The thing is its supposed to rain tonight so im not sure what to do bc i did have a picnic planned for some time. We go out to eat alot so i guess i could take her dinner. im old enough for a bar but she is just 20 so thats out. If i ever ask her what she wants to do or likes to do she just says "i dont care or i dont know." I feel like a loser sometimes bc i dont have a lot of friends that do anything so i cant ever take her out with friends. idk what to do other than a dinner and a movie..
