Hey, glad you are okay. I agree with pp that you seem to be surrounded by cold, selfish people. Your bf's comment was pretty heartless. Why wouldn't she encourage you to take your time? I mean, ffs, what would she do in your situation? It baffles me how so many of the people around you seem to have no empathy or compassion for your situation.
I'm not surprised that things are turning, and not in your favour. The dynamic has never been in your favour, but for the last few weeks, because you had the moral high ground, they've been waiting for your blessing to carry on as usual. You haven't given your blessing, and that has pissed everyone off. You're not playing your role as the submissive, passive, accepts-everything-with-a-smile wife. So their ploy of being patient and apologetic hasn't worked. Don't be surprised if you start getting anger, impatience, heavier gaslighting, more manipulation, from both of them, from now on.
Hold your head high, @Sazdun . You've done nothing wrong. Your husband's 'over it' look is him gaslighting you, as is OW's dismissive response. They're trying to convince you that what they've done is nothing, no big deal, so why can't you just get over it? You being hurt and angry is being dramatic and oversensitive, and there's something wrong with you for feeling and behaving this way. This is going to be the message that starts coming back to you more and more from both of them, and potentially from mutual friends too. Don't let them mess with your perceptions. You can always post here for a reality check.
I would get very clear in your mind about what you want to happen next. It's pretty obvious by now that H is not going to cut off his relationship with OW. You can keep your marriage to him if you don't mind him being in love/obsessed with OW and her being in your life. At least it's crystal clear now what the situation is. I'm sorry it's so shit, though. You need a mate who will rage on your behalf, I think!
