When DH struggles to forsake all others

[Namechangeymcnamechange11]

I have been married for 3 years with a 2 year old DC and one on the way.
DH is up to his 3rd occurrence of messaging other women on FB messenger/tinder (the first time).
I accept my first mistake was believing him the first time that it would never happen again, but since then there's been twice more and one and a bit children.

Please no comments about "why did you have children with this man" - it's done now.

He's never actually slept with anyone, just talks about it with them. This most recent time, I'm really struggling with moving past it.

I don't really know what I want from this, maybe a wwyd?
Will he actually stop? Am I making a fuss over nothing?
I did toy with kicking him out, but I have a toddler and expecting another, plus it felt like it was me breaking up our marriage and tearing apart our DCs life.

Would he be happy with you having identical conversations with other men? I suspect not.

I sincerely doubt he will stop. He has done this repeatedly now without any consequences - genuinely not a criticism, what I mean is he is banking on you:

1. loving him

1. feeling like you'd be the one breaking up your family (you wouldn't he has done this with his actions / choices in prioritising his penis over his family)

1. feeling trapped and therefore staying.

Personally once I might be able to overcome, multiple occasions, I couldn't as I'd lose trust and respect which are fundamental to a happy relationship in my opinion.

He's never actually slept with anyone

Yet. But he will and then it will be all sob stories, crying that he loves you and the kids, how you just weren't there for him, you were all about the kids, you forgive and "get past it" and he will do it again. Lather, rinse, repeat.

You are not ready yet OP, but one day holding on to this will hurt more than just letting go.
