I had the best night with my amazing boyfriend and friends but I feel like I'm losing my boyfriend and idk why. I cant shake this feeling and my anxiety is high this morning. Idk what to do. Does anyone have any advice???

What did he do or say to make u feel like u losing him??

@Lolcat3000 he was being a little more distant and was secretive about phone calls and talks with my sister.

Then why did u say it was the best night?

@Lolcat3000 because it was nice to have him here for my birthday party. It just felt different
