I became friends with a couple a few months ago. I am single and am not experienced at relationships.
The guy dropped in without warning and told me he had decided to split up with his partner as he thought she had cheated. I said he needed to give her the benefit of the doubt and talk things through with her as they had been together a long time. I am hurt as I think he dropped in on me to make her jealous and feel like I was brought into a situation that I had nothing to do with. I always invite both of them to lunch etc but she only came along once. I value their friendship but want to make it clear it’s with both of them and not him alone which I feel very uncomfortable with. How do I approach this situation please without losing them as friends?
