Some background first: I am 20 she is 18 and is an 8, I got into a LTR with her but because I am in engineering I attend a rediculus amount of school and don't have time for her. She is hot and is good for me because I have secured sex. (still live with parents so I can't bring home random girls) too poor to move out..

My LTR asked me last night if I wanted to hang out today I was tired so I ignored it and went to bed. She is now mad that I ignored her and is insisting for me to make plans for tonight with her. The situation where she nags at me always involves my lack to fit her in my busy schedule. Some of the things I do she views as unimportant like gymming, meeting friends, playing sports. She doesn't say it but she implies that she should trump these activities. Fitness is a huge part of my life.

Honestly I do want to hang out with her tonight but I don't want to submit to her nagging me. I don't want to reward this poor behavior and I want to eliminate it happening in the future. I want her to feel like I have given up my valuable time to hang out, not that it is required.

This is just an example of the nagging. Is there a solution or is having a naggy girlfriend a common problem? I don't want to fuck things up and have a dry dick.
