My partner of 18 months has a friend that he works with that I felt he was too close to. Each time I opened my social media he had either loved or commented on her posts . His comments while seemingly innocent were sometimes a little tongue in cheek. I knew by the way he spoke about her that he thought a little too fondly of her . I never met her. There was no opportunity to do so as we are cities away from each other. He was forever on his phone and I knew it was to her or their work group. I got pissed off with this and got shitty aboutit. I told him I was unhappy especially when he didn’t even acknowledge me on social media and hadni relationship status . His only posts which are rare are about his friends . It improved . He hardly interacts anymore .. it was usually him that startedthe interactions ,and when he does it’s just a simple love or like with no comment .he isn’t in his phone as much when with me but when apart he is constantly on Sm and WhatsApp .he does not mention her any more which is bothers me as I feel like he has gone underground with his friendship. There were feelings there on his part but he says they are gone since he met me . Is there something up?
