. She is moving to her home town in a few days, leaving her boyfriend behind in this city, that might be the slow death of that relationship. I have no idea what kind of place she wil have in our lives. This woman is madly in love with my husband, they don't have an actual relationship, they don't even sleep together (although they have a couple of times in the past), they just meet and talk and maybe kiss, and now they also write each other old fashioned letters. She says that she imagines her future with my husband, me and even SO - in her dream her boyfriend is not there. I like her, I really do. She is like me, only thinner and way more impulsive. She says I am her role model and she wants to impress me. She will show she is serious by not lying to her boyfriend anymore and by not sleeping with my boyfriend until things are settled.

Her letter is cute. She is describing how she fell for my husband, her first impression of him is pretty similar to mine, in that she remembers not his body but his strong energy, and that the first meeting sort of stayed with her before she even got to know him better.

I think that polyamorous relationships (or an open one) is the best way to be in a relationship for the human being, since even if Im in love with someone, no one tells me I cant love somebody else or just want to have sex with somebody else.
On the other hand, there will always be someone who's completely okay with being committed with one lover for the rest of their life, and Im one of those, even though I really respect and admire the polyamorous ones.
Is that a typo and you meant to write your husband, or is she planning on sharing both your men?
