HELP! do u think hes cheating!?

my hub told me hes going out to drink w his cowrker and will only be there for 4hrs. he said hed be home by 10pm. he left 630pm and didnt come til the next morn, 9am. he came and stayed in the garage til 10a. this is the 1st time he actually did this and he didnt even have a hangover! everytime hes drunk he gets sick the next day, this time he didnt. he came home showered and later giving me sex like never before. he actually looks at me again in a long time, thruout when he used to never looks at me. he even rubbed my clit 1st in a long ass time too. i have a feeling he did all those w another woman and he decided to do it w me too cause he felt somewhat bad. he purposely slept over cause my lil bros are sleeping over and he knows i will never cause a scene in front of them. he just said to me that he wasnt cheating on me and for me to not think negative. hes cheated on his ex, what makes me think he wont cheat on me too... hes very secretive w his phone.
