Should I be worried that he has been messaging another woman?

[Mum2one2019]

Hi, so I looked through my partners Instagram private messages because I suspected something. He sells cars, last march 2019 he sold a car to a 21 year old lady which ended up having some problems with so he had to keep in touch to resolve the issues with the car.
He then messaged her on Instagram to say sorry about the problems would you like to come out for a drive to make up for it.
She politely declined but said maybe next time. He then messaged her again saying him and all his mates were going out one evening and would she like to come. Again she declined.
He has since messaged her this January saying did you get my WhatsApp message.
I have checked his WhatsApp and can't find a message on there. I guess he has deleted it.
He then messaged saying are you know designing trainers with heart emojis. She hasn't replied.
She obviously isn't interested but he seems to keep messaging her.
What should I think? What would you do in this situation?
I mean, imagine if she was interested, does that mean he would he cheat?
I want to confront him, but don't want the usual why are you looking through my phone speech, plus I want to keep it open incase I find any evidence of him actually cheating.

Tell him you noticed her number on your phone since your accounts are synced, and you wanted to know what was going on.

he said he shouldn't have to clean in exchange for sex

But he's happy for you to do everything even though you work too? He's the worst kind of person.

Please don't involve this poor girl, either by adding her or making up a story she got in touch with you. He clearly has no boundaries and I wouldn't be surprised if he then messaged her having a go at her.

What's so embarrassing for him is that he probably doesn't realise that she has either cringed, creeped out or felt a bit unsettled by his messages. It's not flattering, it's gross.

I have to say that if my husband was sending creepy messages to someone half his age, especially when they clearly aren't wanting the contact, I'd be disappointed and disgusted by them.

It would change my opinion of them and their respect for women, relationship boundaries and self awareness in a way that (although messaging seems like a small reason in principle to leave a relationship) I don't think I could / would want to have to get past.

It's icky. It would give me the ick.

Take a photo of the messages because he will deny, deny, deny.
I bet you anything he’s trying it on with other young girls or planning to if he gets any opportunity.

Been there... married to a creep too.

He is currently pursuing at 27yo ex colleague who has blocked him and he searches for her every single fuxking day!

He has a history of doing this and after starting up his latest stalk I have now checked out emotionally. I haven't left as we have two young children and don't wish to put them through the pain.

I intend to leave him as I resent him far too much to want to spend the rest of my life with him.
Decide upon what you want and what you do not want.

He is rotten. He is secretive. It doesn't change. His self esteem needs that buzz. Pathetic

Stay strong.

@Mamia77 sorry to hear your story. Your DH sounds awful. From experience I would say leaving while the children are young is far better and less damaging for them than growing up in a house where 2 parents clearly dont get along. I grew up in this environment and it was awful. I'd much have preferred my parents to be apart but happy than together and the whole family miserable x

He’s a complete utter creep. Do not message this young girl and leave your toe rag husband. If I found out a man of his age who has abused his position and her information had started messaging my daughter to ask if she wanted to go for a drive I would flip. Just ew
