Secretive partner

Been with my partner for 4 years and the longer we are together the more secretive he gets with his phone. Its got to the point where i cant even touch his phone without him getting angry at me.

I couldnt get him to help me with the kids because he wanted to stay in bed so i grabbed his phone and walked out of the room and sure enough he was right behind me acting all sweet asking for it back and making ridiculous reasons why he needed it "right now".

Ive got to the point where i dont even care anymore. I dont know what hes up to and i dont even think i want to know.

Im exhausted.
