So my (32) gf (28) lives in a shared house. They are all good friends.

She used to date one of the other tenants. After their break-up, guy moved out.

I came to visit her couple of days ago. There are many photos of the household including the ex on the fridge. It is not like they are kissing in the photos or something but there are many photos.

I feel uneasy because of those photos. Is how I am feeling normal or am i very insecure?
