My GF has been chatting a guy on instagram. I happened to notice when using her iPad and the notification popped up. So I noticed there are like pages upon pages of messages between them. You could scroll up for 10 minutes. This makes me feel really bad seeing as how we've lived together for 4 years.
I didn't read it all but nothing appeared sexual although it reads like low level flirting on rare occasion. I believe the term is emotional affair. I just don't know what to think of it really. Typical lose-lose situation for me, labelled as a creep for 'spying' or I bury this and live with the fact that she's doing it. Worst part is I'm not a controlling or jealous type at all...I just happened to notice with unfortunate timing.
