I agree, I haven't seen anyone excuse it.
I have confronted him, just so it's clear I wasn't trying to brush it under the carpet or minimise what he's done, I was simply wondering if it would be best to have the discussion back at home not while sharing a hotel room with our child who will obviously be there to witness it all.
The two photos are both screen shots from a photo I took of husband and our son in the pool, I didn't notice the two women in the photo obviously, both were in the pool at the time (as were lots of other people). He's shown me the photo he screen shot then from and I can see he's not lying. He said it was a case of childish banter and he's shown me the message from his friend that was in reply to the milf comment he made that went along the lines of "pics or it didn't happen". Both photos are of the women in the pool as I said so are of their heads down to the middle of their bikini tops, all the rest of them is underwater (no one here is sunbathing topless etc). I'm not saying what he's done is fine, I'm still furious and he damn well knows it and he has apologised and said it was childish and wrong etc. He wasn't sat around the pool taking dubious sexual photos of women but he's still done something wrong and I'm still very very angry obviously. I've made it clear how wrong and disgusting it is and he's messaged his friend to tell him to make sure he permanently deletes the photos.
Everyone is of course entitled to their opinions, and if you want to brandish him a creep then I can totally understand, but in 8 years together I've never seen a creepy/perverted side to him and he's never been secretive with his phone/computer/emails. I'm able to get on to his phone/iPad/computer and he's never tried to lock me out of any of these and I've never seen anything like this that's rung alarm bells before.
I'm sure I'll be slaughtered for this post for excusing his behaviour but I don't think it matters what I say unless it's along the lines of "I've divorced him, fed his iPad to an alligator and had him locked up on the local jail" then people are going to label me a gullible idiot who's happy to be married to a lecherous creep.
