I have been with my fiance for 7 years. I am only the second woman he has ever slept with, while he is like my 22nd. The frequency of sex has been declining steadily over the past few years. We have discussed this issue several times, always with him promising to make more of an effort (b/c I almost always initiate) but nothing has changed. Last time we talked he said he only had the desire to have sex once a week, while I want it at least 4 times a week, more if I can get it.
I don't want to cheat, but I don't want to break up. We have a great relationship and a life and a daughter together. I just want to get laid more. Recently I suggested an open relationship. I told him how much I love him and how happy he makes me, but that I'm struggling with monogamy.
He did not respond to this well. He said he is afraid I will leave him for someone and that it's embarrassing for other guys to think he can't please his woman. It's not that our sex sucks, it's great. I just miss getting laid whenever I want and am tired of being rejected by him. (I didn't say this when I suggested it tho). He said it was fine and he wanted me to be happy but I could tell it was not fine, so I told him we need to talk more and set ground rules. He also mentioned that I would have more opportunity and that he doesn't want to sleep with other girls. He just said he'd have to deal with it. I told him I don't want him to deal, if he couldn't handle it we didn't have to do it, it was just a suggestion. Then he said he doesn't want me to be unhappy, and that he would just have to deal with it.
Now, I regret ever bringing it up because he has been depressed and anxious ever since. He said I can't take it back and that it poisons his every thought. He says he still loves me and doesn't want to break up, but, I'm worried I have completely ruined everything. What (if anything) can I do to make this better?
