If she doesn't like your sense of humor now, she ain't gana like it in 20 years bro. I'm not saying don't get her back or don't put effort in, ya know it's young love and the relationships you have now are far more carefree and have the fewest life consequences, so just enjoy dating while you can, doesn't even have to be with her, point is you should pursue one's that are fun. People don't find forever love the first, second, or third time, some don't ever find it so don't sweat this particular relationship too hard when you've hardly had time to look for the right person. There's plenty of fish in the sea you just gata put yourself out there and take a few risks.
