Offred has, I fear, nailed it.
RaRaZ where to start?
This man has effectively set a trap, a test. To see what he can get away with.
Fucking off to another woman, repeatedly, when you were losing a baby is about the biggest thing ever. You HAVE to be able to see this?
As for 'throwing it all away' comment... throw what? a YEAR? That's NOTHING in the scheme of things.
It takes on average 18m to 2yrs for a domestic abuser to show their true colours, so anytime less than this, you have literally NO clue of who and what you're dealing with.
I'm not explicitly saying he is, but we none of us can say he's not. With your background, that actually increases, not decreases the odds of that happening.
Putting abuser theory to one side, you only need to spend a WEEK on our beloved Relationships thread to see women married for 5, 10, 15, 20+ years swear on their own heads that their H would never ever stray, and they wind up wrong.
They most of them say, he gets enough at home too. Sex or lack of it is nothing to do with fidelity at times, it's to do with attitude to Sex in the first place.
you are thinking you've made some kind of 'investment' in a relationship. That's the biggest mistake anyone ever makes. There is no investment, there's no 'yeild', no return.
You have to be ready, willing and able to walk away for unforgivable acts. You haven't and you are letting your BOYFRIEND get away with this.
He's not a DP, he's a bloke you're in a relationship with, but seemingly he doesn't value you, your health or well being enough to stay and make sure you're ok, preferring instead to repeatedly hang out with someone who you KNOW does have respect issues as far as you and your Boyf are concerned.
I think he could very well be abusive actually, his friendship with someone so 'low' and the fact that they both agree that the 'real him' comes out with her, shouts volumes about how he sees himself.
The bollocks spouted about cheating, about how slutty, low and unattractive she is, is very likely to be, perhaps unjustifiably, how he sees his true self.
If his family background dynamic is shit, then i'll be even more sure of it.
I'm not telling you to dump him. I think you should, but perhaps only to nip this crap in the bud, so that he knows you won't put up with it.
Saying you won't let him do it to you again, in future, is actually letting him off this time.
He won't take you seriously unless you say that at the very least you need a break.
What he does THEN will be very telling.
RaRa, you HAVE to put yourself first. that has to happen. Whether you stay with him or not.
This is not the be all and end all relationship you think it is, it's a transition, one for you to learn from. This guy's not a keeper, not without radical personality surgery.
Be brave. None of us are here to attack you, all of us see that you are vulnerable and worth more.
We'll be here for you whenever you need it.
