I know it's hard. I know you want answers.
Let me tell you the answers, maybe it will make you feel less confused:
He slept with both of the other girls.
He wants to use you as a fallback.
He is banking on your having no self-respect if he hoovers you long enough.
Remorse is palpable. It is leaving the other girl, first, and working on himself to address why he always needs someone and can't be happy on his own.
It is not coming crawling back when it's convenient for him.
Do yourself a favor and block this guy. Then, do some heavy reading on baggagereclaim.co.uk and get into IC to ask why you are willing to accept so little from a partner, when you are worth much more.
And seriously FTG.
I only have his word and nothing else.
Yes. And the "word" you have of his is lies.
Your situation sounds a lot like mine except he can't deny sleeping with his ex as she is now pregnant. Of course, he tells me she is not pregnant anymore but umm, duh, like that matters? And I don't believe him anyway.
And I found out subsequently that he was with another girl (in the area tho) because I recovered emails from when he used my PC. They talked about their intimiate night together. He denies it to this day even though he gives me "his word" that nothing happened.
My eyes don't lie and neither do yours. There is no point in contacting any of his ex's. You know the truth even if it isn't the truth you want.
Aside from that, do you really want a guy who can't be alone? I'm sorry but any guy who said that to me I wouldn't feel flattered. I'd feel like just another stepping stone until he finds another. But of course he won't leave me and go to that new person until they give him the green light.
Your XWBF is dysfunctional and unhealthy in more than just one way. You deserve to take some time alone, level set yourself and find someone healthier.
Take care of yourself!
Trust your gut. He is lying through his teeth and will continue to do so as long as you let him.
He's not the prize here, friend. You are.
If you have no kids together I'd block him on FB, your phone and email. Hang up if/when he calls for a different number, delete and block emails he sends from a different address. Call the cops if he shows up in person and won't leave.
He is trying to make you OW#4 to his OW#3? Motherfucker.
Please read the Hoovering thread - this is what he's doing. They all do it and it is all bullshit.
DO NOT listen to his pretty words, watch his actions.
He is showing you who he is - believe him.
But you can get there. You can learn how little he is worth, and how more much you deserve. It's a long journey, but the destination pays off!
