Was he cheating?

Some things popped up that suggested he was

Suddenly now he is all snuggly and wanting kisses and hugs more sex

Before we NEVER were hugging kissing snuggling etc

sex is A LOT more frequent and he is lasting longer PLUS? He is doing things HE NEVER did using toys, eating me out...

He is now saying I am pretty and our whole relationship he never once said thatto me EVER

However now he is all I am ugly my dick is little never or barely works out anymore...

Before all this he was working out, felt good about him self, showering all the time etc

Since i called him out on everything he has changed WHY???
