This is a mostly hypothetical, but it's based around something I'm really dealing with.
What if you became attracted to a friend of your S/O? If you felt that you had more in common with this other person than with your S/O? If this person had told your S/O that he/she finds you to be attractive? How about if you and your S/O had been on the rocks for awhile, and you were already thinking of separating? Is it ever alright to date this person, after breaking things off with S/O? Imagine that they are not particularly good friends, but were working on a project together.
Do you think loneliness/boredom can lead to looking at other individuals in a manner that is sexual or emotional?
This man engages me in conversation whenever he comes over and we're around each other. He also added me on facebook. Should I avoid him from this point on? Should I tell S/O what I'm thinking?
Some background: My only other long-term relationship turned into an open relationship, where I was dating around and the guy was talking to other women. It ended up going awful, and we are no longer friends. So I have some fears, yet I feel that I am meant to be poly, and have addressed this with S/O when we first got together. He seemed interested for a short time, but it never panned out. Now that we have a daughter, I don't see it happening (at least not anytime soon, and would not be good to do while our relationship is in trouble).
