met up with an old friend

so when I was younger I had one good mate and he was a guy.. I’m in a relationship now 5years and the old friend asked to meet for some lunch and a catch up I run it past my boyfriend and he was fine about it.. but for some reason it’s just felt really awkward there was a lot of small talk and yeah we brought up old memories and laughed a little but there was a lot of ‘can’t wait to go home and chill out’ like it was forced a little and just wasn’t the same as when we friend when we was younger and for some reason I just feel weird that I even went🙃
