I've missed him a lot but I've been mostly fine, except tonight he was at a party and uploaded a snapchat story of him and an attractive girl with the caption "Bae"
I messaged him "Really -his name- ?" and he replied by saying "She's my friend -my name- "
Should I apologise for what I said, and if so, what should I say? I don't want him to think that I feel bitter towards towards him because I most definitely don't, I just miss him and seeing that hurt me at the time :(
