You mention upthread about 'starting over'. You won't be 'starting over', you're simply deciding to take a different road to your future. You have your children and your friends, you have good memories to keep (he'll fade out of them in time), you have your home (don't sell it yet, your feelings may change). HE's the one who's 'starting over' with his floozy. Much joy may it bring both of them.
As far as 'can you forgive', for me the answer is no. And I'd feel no need to. But the bigger issue is the broken trust. I could never trust a cheater again, no matter how long we'd been married. A marriage without trust is like a broken plate. You might be able to glue it back together, but it will never be as good as it was, it'll never be 'whole' again. You'll always see the crack and think "That's where it broke". Best to just toss that broken plate and get a brand new one, a new life.
And I certainly wouldn't want to live a life where I had to feel constant suspicion, wondering where he was or what he was doing. That's no life at all. I'd rather live on my own, free and happy, making my own decisions and living according to my own lights.
Or can they truly love you and cheat ?
No. Love and cheating are incompatible
I honestly don't think i can live my life questioning all his behaviours .
You shouldn't have to. You don't have to.
I'm really sad over the whole suitation and breaking up the family
Remember, you are NOT the one 'breaking up the family'. That blame goes squarely on his shoulders. It's common for cheaters to say that the wronged spouse is 'breaking up the family' when they tells the cheater to get out. That's the same as saying that the wronged spouse should facilitate the cheating and help the cheater 'maintain their reputation' by keeping silent!! It shows just how egotistically a cheater is. All about saving their own skin and sacrificing the wellbeing of a spouse who has been nothing but loyal. Fuck that cheater and the horse they rode in on. And they stable they keep it at!!!
