My girlfriend is very busy going to college. She doesn’t even have time to send me a text message or call me on a busy day. I can’t figure it out and feel very sad.

Maybe she is really busy...if she joins a club or something else, and if she loves to study, she will be very busy, so you can learn to care about her and be tolerant...If you still feel something is wrong, you can Ask her regretfully how her current life circle is to see if time and space are holding you back... If she becomes annoyed by these questions or gets angry with you because of asking questions, it means there is a problem between you, and it doesn't mean that you no longer love each other. ...I just have a mistress...I hope you will adopt it
