I want to ask you what you think is happening. Several times my girlfriend comes home at 4 or 5 in the morning and finishes work at 23:00. She says she was with friends and slept until the next day because she was tired? She is 21 years with fit body and definitely attracts male attention. Do you think I have anything to worry about, what is she doing?

You should politely offer to be their designated driver. If she objects worry.
Yes you have something to worry about. Be it your insecurities, or her playing you, you should be worried!
Either put her first in your life, & be the man she cant live without, or realize there are many more men out there who will!
