We are a lesbian couple, we've been married 2 years this month. I've recently told her and she said she always knew it was my kind of lifestyle. She hates it though and we don't really know what to do.
While she does appear to know you well enough to guess something like this before you told her, do keep in mind that this situation is new and something of an emotional shock to both of you.
For you, from thinking of it, you've taken the first scary step to admitting it to her. It is likely very different from knowing for yourself alone and you will tend to be reactive and sensitive in this time and generally feeling very strongly about your disclosure and poly in general.
For her, you telling her about it is vastly different from her thinking you may be poly because it is now a stated reality between the two of you as opposed to her insight into you.
Both of you are new and adapting to this being a stated reality between the two of you. Answers may not be immediately evident if your initial responses are very different and you both care enough about each other that going your own ways is also not an obvious choice. Give it time.
I feel like a part of me has been missing since I tried to be mono but I love my wife and want her to be happy too.
Naturally. Whether it is possible remains to be seen, but neither of you are entering this selfishly and that is a positive thing.
At first she said she would try it (while crying) and then changed her mind and said she couldn't do it. She can't handle the thought of me with another woman. I don't want to hurt her.
I would suggest that you reassure her that nothing is going to happen unilaterally and that there is no hurry to make up her mind (or yours). It is a complex mismatch of needs that allows no solution with full joy upfront. So don't conclude in a hurry.
In the meanwhile, is it possible that the two of you have conversations regarding poly? What do you feel the need for? What do you have in mind? What kind of situation would bring you joy? What disturbs her about poly? How does she imagine you'd be with another woman and in what way it bothers her?
Getting into details without hurrying to conclusions allows you to potentially chart a course through a minefield. Perhaps you may not get poly fully as your vision, but you may have the things you most long for. Perhaps she may not have you as exclusive as she prefers, but the manner in which it is done does not trigger her worst fears, reduces her feelings of being threatened and thus both of you are able to continue your relationship.
Because if you can't find a middle way, the answer is obvious, but painful. One of you sucks it up and calls it life, or you separate. This is what you have available to choose from at this point. It isn't something to look eagerly forward to. So you might as well take a lot of time exploring just what you want or don't want in a lot of detail to find places you can agree. Always remember, conceding some parts on both of you will make it easier for the other to compromise as well, because that attempt to go beyond own preferences for the joy/security of the other is a direct statement of love between the two of you and very reassuring that whatever happens, the relationship is not being threatened.
Any advice? Please don't be rude or nasty I'm just looking for advice no judgement.
Why do people use such cliched lines? I didn't even have cause to be nasty till I read this. We say what we believe is helpful to offer. Take what seems useful to you. And sometimes a verbal kick in the butt is worth the weight of the laptop you read it on - in gold. Are you really so sorted in this situation or flush with ideas that you can afford to be picky on what you will accept as a suggestion based on what you think of strangers on an internet forum?
