Guy I’m seeing has said his ex is attractive a bunch of times.

He shouldn't be mentioning his ex to you at all except to admit she exists and he has kids with her. The fact you say you think she's very plain is a bit rude. I'd rather a man was kind about his ex than branded her a maniac with no redeeming features. But it still sounds a bit crass.

How would he react if you said the same about your ex? I mean, presumably people don't go out with eachother long-term if they don't find eachother at least vaguely attractive?

The fact that she is not particularly attractive, yet he still thinks she is beautiful would sound alarm bells to me.
He is still smitten.

I wouldn't like this. The cynic in me thinks that he WANTS to make you feel insecure. Do they call it negging, these days?
Anyway, it doesn't matter if she is actually attractive or not. It's the intention behind his words that is questionable.

Either he still has residual feelings for her or it’s a weird form of negging where thinks you’ll want him more if he compliments another woman.

Either way, I would run. If you have to see once more, do what @User09678 suggested and talk about your incredibly attractive ex to see how he reacts.

I suspect he is still in love with her and you are one of his rebound relationships.

I am sorry.

You've only been seeing him a few weeks and in that time he's repeatedly talked about his ex and how attractive she is. He's bringing this up proactively. I don't think he's over her and given that it's such early days, I would be inclined to end things with him.

I think that for most people, both men and women, the early weeks of a healthy relationship are the exciting ones where your new partner is in your head all the time and you're thinking about how much you fancy them etc. In a healthy relationship, these would very much not be the weeks when your ex's attractiveness keeps popping into your head, to the extent where you keeping mentioning it.

Even talking to a new person he’s dating about how beautiful he finds his DC is poor social skills IMO.

Oh goodness no. Dump.

It would be a case of

Hi babes'

Bye babes'

For me 🙌🏻

Saying it once in the context of his children being beautiful - fine
Saying it everytime you see him - not ok.

For me it points to either him not being over her or him wanting you to change in some way to be more like her. Eg - you say shes quite plain. Maybe she doesn't wear much make up and you do and he prefers less? Not saying this is the case, but maybe something like that, maybe the way you dress?

Either way not a good look.

A lucky escapee?

He's not over her

I had this, but he further qualified it by saying he had enough of drop dead gorgeous woman. He said it to me. So what did that make me

I'd give him two more chances. Next time he mentions her being attractive I would say "I'm well aware you've said that a few times now. I wish you'd stop saying it though as it makes me uncomfortable with how often you say it". Then the next time I would probably just say "I've told you before it makes me uncomfortable how often you say how attractive you find your ex, why do you keep doing it?"

Then I'd bin him off. Warning shot and then move on

Let's be honest - the ex is always a risk in a relationship because it's hard to cut off feelings completely when you have been in love or lust with someone for a long time. And they have kids together.

he has mentionitis!! there is no reason to mention an ex's looks on a date! He can't stop talking about her because he is probably still in love with her.

I would listen to your instinct and move on here.

How old are the children? When did they end their relationship? It’s refreshing to not hear him talk badly about his ex but…. it seems he may not be over her unfortunately x

Get rid. Whatever the reason for it it’s not something you want in a partner. It’s challenging enough being in a relationship with someone who has children from a previous relationship without adding anything like this to it.

Oh no fuck that. I have no problem with occasional remarks about a celebrity etc but I don't think other people's attractiveness needs to be brought into a relationship on a regular basis and it needs to be done with tact. It adds nothing and can take so much away. Especially if it's someone close to home like his ex. Don't second guess yourself on this. He's being tactless. If it was a one off as in pic of the kids 'ooh aren't they adorable ', 'yes they take after their mum, luckily for them!, fair enough. But it's a pattern. Why would he think you'd want to hear his ex's looks praised repeatedly? It isn't appropriate.

He's still into her or he's trying to put you down in some way because he's insecure. I once had a very short relationship with a guy who kept pointing out other women to me while we were out and about and telling me they were hot, cute, pretty etc. He never said those things about me. I know this will come across as very vain but I know I was more attractive than those women he would point out and him himself. I was a model at the time and got a lot of attention myself. And I think he just couldn't handle that and it was a way of letting me know I'm not really that great. I stopped seeing him because every date would leave me questioning myself. If he's not making you feel good then you have to end it.

I don’t think there is anything wrong in what he is saying. It wouldn’t necessarily concern me and far preferable to hear respect shown to his ex than she is crazy etc

but it’s how it’s said and how often

seems you are picking up on him not being ready for a serious relationship yet

He still holds a torch for his ex. It’s too soon for him, move on.

Goodbye my lover….

He's not over her. I wouldn't waste your time.

At best his comments about his ex and DC show poor judgment and social skills. For me it’d be ‘ick’ territory and enough to stop seeing him.

Ah yeah fuck that. I think he’s dating too soon after a break up.
