Aibu or this flirting

[Lilmis]

I feel Like AIBU but I felt like DH was flirting with a girl on the phone yesterday. He called his brother to wish him for his birthday and instead a girl picked up. The girl must have said something bout his brother being good looking and DH was like I'm his older brother like he was implying he's good looking too and had a nice 5 min convo while I was just passing time sitting next to him. Then his brother sent him a pic of the girl and DH txt back saying the wife is jealous.

Was annoyed as DH once thought I was flirting with someone and I clearly wasn't. He got in a huff.

What do you think?

Sounds like there's some growing up to be done for both of you

I used to have the same banter with my FIL. I used to say that my DP was his 'wannabe' etc. I like flirty banter and don't mind if a partner does the same.

That's irrelevant, though, because if it really bothers you then he should respect you and try not do it in front of you. The banter could be thought of as him not changing his personality for you, which is fair enough, but the photo etc was out of order.

Sent him a photo of the girl if I was that girl I would find that seriously weird. Sounds like the 3 of them were having banter, if you don’t like it tell him.

One person's flirting is another person's friendly.
I would have no issue with my dh being friendly with his brother's girlfriend.
Sending the photo ..... hmm.... a quick snap of them both - no problem. Another pic or her - getting into 'odd' territory.
Although, tbf, it was your BiL that did that, not your dh.

Sounds like harmless flirting.
Tbh, I've sent dsis a pic of a guy I've dated so she could have a look.

BiL has a girlfriend and this girl was a random work colleague who he was saying he needs to whip, in a flirty manner.

Right........... the whole context is changing now.
"Needs to whip" is not what I would say was 'flirting'. I also think it odd that a 'random work colleague' would answer your BiL's phone.
