Hi OP,
Sorry your going through this, the pain is indescribable. I found out my DP cheated on me a month ago, different circumstances but the pain is the same.
My first advice, is that it is too fresh to even think about forgiveness yet. I’m 4 weeks in and forgiveness is not on the table yet, but acceptance is your first step.
My second bit of advice, is don’t try and make any decisions right now - because his actions will help guide you on the way through.
He firstly needs to end the affair, for good. And erase any contact he could possibly have some said women. And he needs to put you first no matter what.
Can I ask, did you ask him to leave, or did he leave on his own accord?
Actions are far far more important than words.
I believe it is possible to be in a better place following an affair, but it will take every bit of emotional effort you both can give. It needs 110% from both of you, and it isn’t a path for the faint hearted.
The easiest option will be to separate, that honestly would be the easiest thing. But as you have said you want to stay, I just want to prepare you for the difficult path you are going to face.
You are still in shock, and will be for awhile. Don’t expect to understand your emotions or even control them yet. I went for sobbing my heart out to screaming that my DP is a complete c*nt in less then 2 seconds. It’s confusing, it’s draining but it’s needed. Don’t suffer in silence and don’t downplay any emotions because they will only return to haunt you.
Honesty is the only way to understand whether you can aim towards acceptance. My DP asked every intrusive questions I asked and I believe he answered honestly, there are things I wish I never asked as they make me sick to my core - but to be able to get a true picture of what your up against, you will need to know the horrid details.
Please feel free to message me privately any time, I will happily give any small bits of advice I can. Be kind to yourself OP, don’t blame yourself or question your actions. You did nothing to cause your DH to make this choice xxx
