To find partner mentioning this woman a bit irritating

[Teacher7676]

It's one of his friend's girlfriends, I've never met her. He's known the other guy for a few months.
He told me that the girlfriend really likes him, Which is great.
Then he said it again a couple of weeks later.
Then a few days ago she apparently said to him that he had a lovely smile, and that this was why he was likeable, he told me this.
Then I said oh that's nice to say, then he said in a jokey way, "Because she actually rates me, unlike you."
I had no idea why he said that, i always give him compliments and do my best for him.
I don't know if he fancies her, don't get why he needs to tell me that she really likes him, twice?
Maybe I'm just being jealous?
It's great if they all get on but it just seems a bit much

Short of insisting he has no contact with her, not a lot tbh. If he fancies her, she'll either reciprocate or not, and if she does reciprocate they'll either get together or they won't. You're as good as powerless.
Obviously you don't have to facilitate them by being OK with him messaging her, meeting up alone with her and so on. Nor should he be making a fool of himself and you by going on about her, so I'd tell him to cut that out.
But otherwise, you just have to keep your fingers crossed that he values your relationship enough not to be tempted, or failing that, that she doesn't give him a chance.

He’s proper loved up op. To such an extent he’s even telling you. He can’t stop himself. As said. I’d bet good money she’s not interested.

what do you mean my partner? Do you live together, how long have you been together, are you married, kids? I’m hoping you’ll say it’s just your boyfriend and can get away. As you can see most women find this a level of pathetic too far.

How long have you been together?
Are you 'tied' together? Kids? House?

The right thing to do is to talk to him about it in a mature way when both of you are calm and have time.

The tempting thing to do would be to start mentioning some bloke (best to be an imaginary one) who has said they think i'm pretty and then says you have a nice smile and wait for his reaction.

What did you say to him when he said she rates him, unlike you? That was a nasty remark from him.

I would have said "but I know you" and given him a very meaningful look.

I mentioned it and he apologised and said it was only meant to be a joke as i compliment him a lot. Feel a bit silly now

I find it weird and inappropriate that him and his so called friend's girlfriend are chatting this way. It's disrespectful to his friend and also yourself.
Maybe you should have alternative plans for your future.
He also fancies her

He also said he's only ever met her once

Also I think she actually said the smile thing to her partner rather than to mine.

Mentionistis. Sounds like he fancies her. Doesnt seem to be any other reason why he'd keep bringing her up or steering the conversation towards her.
She may fancy him back or just be friendly, you won't know unless you see them together.
He sounds like a pathetic kid, especially trying to put you down for not giving him compliments like she apparently does. Urgh I'd be massively turned off. Crushes are fine but most men have the sense to zip it around their partner

You shouldn't feel silly. He mentioned her on 3 seperate occasions and he's met her once....

Next time he starts waxing lyrical about her say jokingly "you're talking about Jane again,best bet careful,you wouldn't want John thinking you fancy his GF"

If that sort of behaviour is fine in his world start talking about this really hot man you met somewhere with the most intense blue eyes (or brown, green whatever).

This is interesting concept because I have an ex that did this all the time; we weren’t together long as he was just constantly trying to make me jealous - it was so pathetic, boring and offensive.

I tried to flip the script once and did it to him to prove a point and I can honestly say I felt like such a weird nasty bellend even forming the words.

Experiencing that feeling of being some boastful arsehole referencing other hot men and intentionally hurting your “partner” was actually horrible and knowing he does that by choice/enjoys it was the end (it was already dead at that point tbh!)

nb not necessarily relevant to your situation op!!

I don't know why you would feel silly.

He sounds like a right tit.
