Does anyone else worry about this?

So i am going to be 24 soon and i still don’t have my career (one year left of nursing school), so i’m personally not looking to really get married or anything until a few years. However, i think that dating rn is really important and it’s important to take it seriously. I’ve been dating my bf for five months, things have been going well. Quarantine has got us a little stuck tho and we’ve had a little bit of issues.... he wouldn’t be as romantic as before. I talked about this with him and now he’s better. I also feared that he was just using me for sex. But i talked about that with him too and he denied it. Now for all my ladies that are around the same age as me or older, did you guys date to have fun at this time or date to be serious? Cuz i feel like i’m heading to a heartbreak if he’s dating for fun and i’m dating for serious.
