Am I being paranoid about my Girlfriend cheating on me?

My girlfriend and I had a fight that made her tell me she wants to break up. She then says she's finally "free". She goes missing for some days, finally picks up the phone one night. It actually sounded like she was having sex but trying to hide it. II turned up the volume on my headset and it actually sounded like bed shaking, kissing, etc…

I then ask her to have a video call through skype, and she agreed.during the video call though, she wouldn't show her face, or show me around the room, instead she puts the iphone on the edge of the bed. That makes me think she's hiding someone there. But obviously this isn't really proof, it could just me being paranoid?

Its very hard to be certain a girl is cheating unless you catch her in the act. In your situation though all the indicators are there. Especially the part about hearing noises such and her feeling better. I would not come out and accuse her of cheating though. Do not do that unless you have some solid proof. You will lose a girl you really love if you do.

On cheating too, you should be aware that cheating these days is more than just something physical or sexual with someone else. Anything external or emotional that takes your partner from you or makes someone more important than you is considered cheating too. Many do not realize this at all and are cheated on in this way.

You don't really seem to know what's going on. Maybe you should talk to her in person and confront her with your questions? If she stays doing stuff like this, then maybe she isn't ready for something serious. Maybe you could talk about this with your friends? Friends can usually tell if you're being paranoid or not. And if not, maybe they can help?
