Partner texting another women

[HBXO]

I'm looking for advise.

Me and me partner have been together for 4 years and have a four month old baby although we have been arguing lately.
Tuesday things come to a blow and he said he was going back to his moms, not even 30 mins later he is texting a women he used to work with...(we have each other's passwords to Facebook this is how I know.)

At first nothing bad but friendly but then it became flirty etc. When I went to have a chat later that night to sort things he had blocked her and wasn't going to say anything but I had to air it for to move on. When we first got together he did this and hasn't for years. I just feel so hurt he had started talking to someone so soon.
He now wants to sort things.. do I stay or go I feel so hurt 😢

Any advise would be appreciated, sorry for the lengthy post!!

do I stay or go

What do you want to do?

Was it a woman he knows? An Ex?

It's worrying he's done it before. I just wouldn't feel safe that it's a one off.

I have no idea my head is in a rut, of course I love him and I trusted he would do this.
Yes he knows he she used to work with him but has now got a new job elsewhere x

Having been in a similar situation, I think it's wrong that the first reflex was to start looking for other female attention.

I still believe that if the man is truly interested in the relationship succeeding, going for space is fine, to clear his head, to allow you to clear yours etc, but it is not fine that instead of his priority being, "what should I do if I want to fix this relationship" but to instantly look for attention from another woman.

Courtney555 - This is what hurt the most, it's 4 years not 4 weeks and the thought of him doing this is making me think does he really care. Hope y ur situation worked out okay x

Alas it didn't. Or maybe not alas when I think about it.

Do you feel like plenty of things in his life he happily makes a priority, but you don't factor in?

He makes his daughter the priority which is good but apart from that he factors me in. He tells me he loves me and that he couldn't be without etc but this has literally made my head spin and I just don't know what to do. X

Is he apologetic?
Does he acknowledge it was wrong?
Have you asked how he's feel if the roles were reversed?

If this is how he reacts with an argument...it's immature and doesn't bode well for the future.
