So I and my girlfriend have been together for 9 months now. I never check her phone as such but I did on 2 occasions. Once in April and another 2 days back. I noticed she had texts from the same guy. There wasn’t anything sexual or anything doubtful about it but I saw the call log which showed that she’s spoken to him twice in January and once in August (which was for 3 minutes). She’s rejected or missed (Ignored) all the other calls. I tried that number on beenverified and it’s some guy who she perhaps had been friends with or maybe gone out with on some occasions. The last text I saw from the guy said ‘tbh if my texts bother you then I won’t. I don’t want to get you in trouble’. She’s replied to him curtly saying ‘just working’ when he asked her what she was upto. I wonder who this guy is and should I ask her about it.
