AITA for how I reacted when I came home and found a young lady in our bedroom.

So I (37F) and my husband (40M) are kind of health freaks and we always insist on taking our son for a walk before breakfast to activate the metabolism.

However when we got back this morning I find this blond bimbo has let herself into our house ( with a key my husband swears he didn't give her)

Not only has this bitch helped herself to my son's food but she's curled up in his room as if she lives here.

Here's where I might be the arsehole, I lost my temper and accused my husband of having an affair.

He denied it and I will admit I ate the girl before I could get her side of the story.

But am I seriously supposed to believe my husband when he claims that "he has never seen her before." ( Especially given his internet search history).

Right now things are tense and I've taken my baby and gone to stay with my friend and her kids in their shoe.

So Reddit, should I give my husband a chance to explain or trust my instincts and move on with the separation?
