i've just discovered that my partner is regularly texting an old work colleague and close friend from years ago, I did'nt know my partner at the time of their friendship and until recently had never heard her name being mentioned.This person came into his life again recently briefly I thought and had visited us once to pay her respects to us when a family member passed away. He never mentioned their friendship apart from to say that they were very close, I don't have a problem with him having friends, texting them this person is great was really friendly when I met her, she is married with two children I dont see her as a threat not like his ex but to be honest he keeps things from me that I wouldnt dream of keeping from him.I wonder if her partner knows his wife is texting my partner and if he is ok with it? When we met on the one occassion she ,mentioned her husband had questioned why she felt the need to visit my partner after all this time. The fact that he didn't mention it to me is that a red flag? Or am I completely paranoid? I go along quite nicely thinking I know all is open and honest and then i find out a little thing that I didnt know and feel he's been secretive when i would never be. now i just feel like an insecure paranoid mess! Am i?
