Sketchy.?

Edit:: I would not just randomly ask my bf to see his phone if he never did what he did. He cheated my whole pregnancy by sexting and snapchatting a bunch of random girls. He never met up with any of them , but it's still cheating. Our son is 3 months old now..

Long story short ; I asked my boyfriend for his phone. He said why. I said I just wanted to see it. And he responded with "no. I'm not giving you my phone. "

So I said; "okay. I tested you and you failed. I wasn't even going to look through it. I just wanted to see if you would of handed it over."

He then said ; "well. Then here's my phone if you think I'm cheating on you." -as he holds out his phone to give it to me.

I then said no I dont want it now and I went to bed.

Is this sketchy?
