You know what they say, kids make the best birth control. =x
I think I'm going to start using initials to refer to my boyfriends now... Live in boyfriend and LD boyfriend is too much of a pain in the ***. So for future reference, Live in boyfriend is J, and LD boyfriend is E. So anyways...
NRE is awesome. You just have to be careful, otherwise you can get yourself into trouble. That's with or without poly, but with poly it's even more true. I had a relationship last year that lasted about two months. I was stupid for getting together with the guy anyways, as he was in the process of getting a divorce with his high school sweetheart after they tried to go poly and she just ended up leaving him for the other guy. I don't really regret it, as it was a good learning experience but it was definitely painful. He and I had a lot of stuff in common and were more matched up sexually than J and I are, and since that was my first poly relationship, I didn't really know how NRE was going to affect me in that situation. I was seriously considering making this other guy my primary, and J a secondary (this was back when I thought you could only have one primary). After things went south with this other guy though, J was there for me. He supported me, gave me a shoulder to cry on. I realized that no matter what happened, he was always going to be there for me.
NRE with E wore off about a month ago or so. But there's still a lot of passion there, which is awesome. I still get that giddy feeling when I see him, but it's a lot less intense than it was before. We've been together for about 4 months now, and I can definitely see him being an important part of my life long term. It'd just be a lot easier if we lived in the same town, instead of an hour and a half apart. =/ It's not a permanent situation though. In another year or two he said he'd feel a lot less guilty about moving out of the house that him and his other gf N live with his wife and her bf. They helped support him while he was going back to school for massage therapy, so now that he has graduated and has a job, he wants to stick around for a while so she doesn't feel like he was using her. I still have trouble wrapping my mind around the idea of one's spouse not being your primary, but I understand that people grow apart and all that.
