There are 18 years between my partner and I. We have been together for a little over a year. I knew going into this there would be difficulties. So far both of our families have been very accepting. The only issue I've been having is with one of his friends. I encourage him to spend time with his friends. I know they're not going to want to spend time with a middle-aged woman. I'm okay with that. The problem lies with one particular friend. The friend will want to spend time with my partner (which I'm okay with), but will exclude me from the invite. The friend will bring his gf and often invite another woman. It'll be a friend/sister/cousin of his gf. To me, it feels like he's trying to set my partner up with someone else. Am I being paranoid? Would this bother you?
