90-day relationship : questions

I’ve just watched the 90-day relationship course and I have questions 😉

First, I would like to suggest the idea to my husband, but I feel it being a bit artificial as we’ve been together for a long time, now have kids etc. I find it strange to discuss what I want in a relationship so many years later. What do you think?

How should I present the whole concept to him to make sure he’s completely aware of everything involved?

Also, I find it hard to imagine choosing a why (the 3 values you mention). I think I’m afraid of us not wanting the same ones actually.

Another fear comes with the idea of sharing everything. At the moment, I’m madly attracted to another man. I can’t see sharing this with my partner as something useful, I can consider sharing my wishes behind that (like having more sex with my current partner, in different contexts etc.) but not the full truth, I’d be afraid of hurting him and the relationship without a useful reason. How should I handle this kind of topics?

I realize it’s all quite frightening to me in the end 😉 I’m not sure I feel ready to have my kids suffering from a split. I feel confident about our love but I feel some truths might really be dangerous for our relationship (for instance this attraction I have for this other guy, the physical things I dislike in my husband etc.)

Another, lighter, question I have is about time. How much time should we commit to the exercises ? For instance, I’ve heard “We used to spend 3 hours nothing just the two of us, being there.” I just don’t feel I have enough time to do that long with my job & kids around. What do you recommend?

Thanks a lot and sorry for the numerous questions I submit but I’m really interested in the experiment.
