This may be an odd post, but I wanted to share to see if someone has any insights.
My boyfriend is not only monogamous, but he is also rather -it seems to me - aromantic, me being his exeption of course. He always had big dreams of romantic love, but the reality of his actual life is that before he met me, he had one 3 year long relationship which was somewhere between romantic and purely sexual, and apart from that just a string of one night stands. I used to be a bit jealous of this woman that I have never met - until I realized that it was totally unfounded. Because not only did he not love her, he has never even been truely infatuated with anyone, not even from afar. So, falling in love with me and me in him means I chose the most monogamously mono boyfriend to be in a polyamorous relationship with me.
It sometimes makes me scared that we are so different. Not only am I poly, but he is my third/forth serious romantic relationship and even as I child I would fall seriously in love with people. I am seven years older than him, but still our differences in experience is vast not because of age. He says he is often bored and I think my own infatuation with life has something to do with the fact that I have been so often in love. I can remember a whole of six months or my life when I was not in love with or infatuated with at least one person. I feel there are things about me and also to some degree other people that are hard for him to get because he doesn't share our experience. Not that he is judgmental (his only concern was if he is my first real plural relationship, which he is), he just doesn't get it. I was looking forward to swap stories of our exes and such, but there just isn't any on his end. He got on well with his ex, and he enjoyed talking to her, having sex and so on, but she never challenged him, changed his life or met his family - and he never confied in her. I really feel that I am dating someone who was never in a relationship before. Even he thinks he is inexeperienced for his age.
In a way, we are a perfect fit because apart from poly I fit his idea of that one girlfriend who would come along and sweep him off his feet. There isn't really a problem as such, it is really just for me a life without loving someone would make little sense, I don't understand how that works and I would like to better understand what his life was like.
