I am in an ltr with this girl whom i have been dating for 7 months now. We are going on vacation this week, she back to her place and im going back to my country, so we wont be meeting each other for a month, during which we will be talking on skype etc. However, i have noticed recently that even though she doesnt like her ex's posts and pics on fb, she likes all his friend,s stuff and has been doing that since we dated. I came to know this as i looked at the guys posts and saw that all the profile pics, etc of his friends have been like liked by my gf. Should i bring this up? I f i do, ill look really creepy and it is eating me up from the inside. She is not in touch with the guy as she spends the whole day with me and i have the password for her whatsapp and fb so the last conversation they had was a month or more ago.
