Me and my partner have been together for just under 3 years and everything has been great until recently. About 3 months ago, one of my childhood best friends (happens to be a man) got back in touch with me. Straight away I told my partner straight away and he turned very offish with me and when confronted he said he was fine. I have never given him any reason not to trust me. Every time I speak to my friend, my partner becomes quiet and off with me but says that he's not trying to stop me from having friends.
I'm not sure what to do. Help!
