Should I be concerned about my girlfriend hiding her facebook?

She could be hiding it for any number of non-suspicious reasons... For example, maybe a special holiday is coming up and she needed to ask around to find out what to get you. Maybe she hid those comments so you wouldn't find out about her secret, loving plans.

Also, you might want to ask her to just delete the comments she doesn't want all of her friends to see. It may be a good alternative to making all of them completely blocked.

I definitely think that you should talk to her about it. Communication is key to every relationship. If you let these feelings of suspicion and resentment build up inside of you, one day you might just burst! So talk to her about it ASAP.

Hope this helps! Have a nice evening!
