My partner and I have been together coming up to a year, we've had a great year and no real problems well not till the other day. I notice him texting a lot while we were watching a movie I turned and looked at the screen and saw he was texting him ex, I did see the messages but did see that he sent a horny devil faced emoji I also then found he had readded her to facebook. So I confronted him about it and as we were discussing his ex then calls him, he did answer and said it was about problems she was having with her phone and as he is in IT she thought he could help her fix it. I have no problems with exs being friends but they supposedly haven't spoken in well over a year and now the phone calls and texting. Am I going crazy or does something seem off?
