is it helpful to know that for the first few months of our relationship he was sexting upwards of 20 women? And that he doesn't think that online relationships are cheating if the women are in another state/timezone/country? And I'm 99% sure he was still messaging women via Facebook while I was pregnant this year and in the hospital after giving birth. He also started sexting women november/December last year, so realistically he's only stopped since he finally gave me his password and deleted everything. His email said in September he had 16 unread messages, back in August he had no unread messages but he hasn't spoken to that many people, so yeah. Cheating lying piece of shiny who refuses to leave and turns everything he does wrong back onto me and my "insecurities" that he fucking gave me!!!

Ooh dear he's doing the old switch-a-roo by making you look like the bad guy

Gross. Tell him to delete them. Super disrespectful. I found some old photos of husbands ex in the glove box of his car a few months into our relationship (he said he’d forgotten he had them). I asked him to chuck them and he did (pulled over to the side of road and into a Garbo bin). If he had wanted to hang onto them I wouldn’t have been ok with it.

That's so weird because it would mean the pictures were put on the phone AFTER you gave it to him so it's 1 of 2 things
1. He met up with the ex after you began dating
2. He transferred the pics from the old phone onto the new. Either way it doesn't matter. He is disgusting and I wouldn't waste another minute with that pig if I were you. Good luck ❤️

Yeah I wouldn't be happy.

He basically gives you no self worth? Honey, self worth has to come from yourSELF. Getting away from this psycho is a step in the self worth direction.
Think of it this way: if, in 20 years time, your daughter came to you with a problem just like this; what would you say to her? Would you say "oh sweetie, you need to stay with him and keep pushing. It's obviously all your fault, and you deserve to live like this"? Or would you say "darling, that guy is a dick, and you can do so much better"?
I'm sure you also find other men attractive at times, but do you then make a fool of yourself and your family by acting on it? I'm guessing no. Like normal people, you probably appreciate the beauty in front of you, maybe even store it away mentally as some foreplay fodder, and move on.
Why is he less accountable for his behaviour than you are? Is it because he has a penis? Is it because he didn't push a baby out of his body (either way of birth)? The answer is no. It's because you allow him to be less accountable than you are.
Fuck. Him. Off.
This shit is bananas - D I V O R C E !
Leave him, take the baby with you, get a solicitor, and take half his stuff (usually I don't suggest going through a brutal divorce, but fuck him). And put an official parenting agreement plan in place ASAP.

smash his head in

If he likes having the photos to look at, based on his past behaviour, (sexting while you were in a relationship, and most defintely if he did that while you were pregnant and in hospital - major red flags), and also on how he projects all the fault onto you, I would suspect that he is an infidelity waiting to happen, if it has not happened already.
If I was you, I would start getting financially organised to leave. Money set aside etc.
For when it is convenient for you to leave.
Online sexting is definitely emotional cheating, and I would suspect he would turn it into reality anyway if he got half a chance.
Just chronically unfaithfull by the sound of it.

It’s hard, iv got a box of old photos of my ex.
It’s mixed in with all old photos but that doesn’t exist anymore does it?

I wouldn’t throw them out if hubby wanted me too and I would not expect him if it was reversed

Iv still got some ex’s on Facebook albums.

But this does feel a bit off.

Are they nude photos?

We've been together two years and have a four month old daughter together. He also blames me for him constantly checking out other women when we go out together basically gives me no self worth.

I’d be upset.... I’d also want an explaination as to why they’re on his phone.

Leave him! Get out now before it gets worse. There is ZERO reason he should have old photos on a new phone. If he’s openly stated he’s trying to control you by doing such a thing, get out.

Absolutely you should be upset. This is disgusting behaviour and an absolute lack of respect for you and your relationship

Depends how long you have been with him. I don’t expect a current partner to pretend he doesn’t have a past, but I would expect my husband to remove any physical reminders of past relationships that I was uncomfortable with. Imagine the kids - Daddy who is that? Oh just some slag I slept with before mummy 🤮

Upset doesn't even begin to describe how I would feel.

I would be very upset if I found pics of my husbands ex on his phone. And even more upset if his response was I’m insecure and controlling. What kind of a reason is that? He got busted and he’s projecting onto you I reckon.
