I don't know how to talk to you anymore
How about just giving it a shot? Try talking to me.
I don't feel the same connection with you anymore.
While it can be more difficult to talk to a person who  you don't feel a connection anymore, it is not good to stop talking to them. You cannot fix this and form a connection again if you don't communicate.
You are just too fucking sensitive to me man, fml.
Im just trying to be nice to you. Instead of getting upset how about appreciating that someone took the time to try and talk to you? If you make people feel unappreciated they will avoid talking to you.
