She's returning home for in house separation!

[Oxford1]

I desperately need advice here.
We spent the entire day so far together

We went for a walk and somehow got into relationship talking which led to is talking about me VS om

I have to focus on not bringing him up.
I ended up saying some stuff that she probably filed away in her brain
I have to realize that she could repeat this stuff to him when they talk.

I know she's texting him and he's Sexting her
I also know that he is going nuts that she's home

Can you believe he made her promise him that she would not have sexual with me?!
I am her husband! I think it's because she has mentioned he [censored] in bed!

I realize that when we are together he can't come up.
But I don't think she is really in love with him! I thinks he's her dad uh
She does say thigh he immature and a dope!

I know we had some abuse but I don't see her leaving me just for this

I really am In love with her just spending time with her we have such a bond but she's still feeling like she's eventually going I marry this guy!
