So I’m (F30) in a long distance relationship with this guy (M35). We work in the same office. He works from office while i work remote. He was never close friends with anyone in the office but one time a group of them went out after work and then they went out again a few weeks later. After this last night out he wouldn’t tell me nothing. When I asked him the next day about it he was like it was just a chilled night and I don’t remember anything. Which I found suspicious. I also noticed that him and another girl started following each other on social media from that group and mind you he never followed anyone from office before this. On asking him about it he was like “lol i accidentally followed her” like bro what? He’s also been very weird with me like he would share nothing and he would always be in a hurry to drop the call giving different excuses whenever I called him. I don’t have any solid proof things just don’t add up and I have a strong gut feeling that something is definitely wrong. I don’t know how to get proof because my colleagues are not my friends so i can’t really ask them anything. Do you guys think something is definitely wrong or am i overthinking this? Please help!!!!
