Distance relationship-unsure about moving, boyfriend has no doubts
My boyfriend and I dated for one year together in NYC and we have continued the monogamous relationship for another year coast-to-coast. He took a job in CA, as he was unhappy with his job here, and I gave him my blessing to move there, telling him that if we were meant to be together it would work out (I don't really want to settle down in NY anyway so there was no reason for him to stay here unhappy). I seriously have considered moving to CA but after a year in separate cities am still unsure. He feels I am his soulmate and said he would propose if he knew I was ready. He had an offer to move back to NY, but again, I felt that since neither one of us really wants to settle here (he is from CA, I from MN) it didn't make much sense. I had wanted to move back to MN before I met him to be closer to family and still think about that option (he said he would move there but it would not be ideal for him).
We communicate daily and have had the opportunity to see each other fairly often. We share many similar interests and have fun together... I do love him very much but I am not sure I can say 'soulmate' yet... I am trying to figure out what I am so unsure about. We met online and my instinct is that we are extremely compatible but that perhaps we are lacking in chemistry on some level, if chemistry exists. I am physically attracted to him but have felt more attracted to other partners. On a physical level, I don't think he is doing anything 'wrong,' as far as affection is concerned. I want to kiss him and smoosh his face but don't necessarily have a strong sex drive with him (although I am interested sometimes). Also, we have good conversations but I feel I have a strong interest in philosophy/spirituality that we don't often touch on.
My question is, do you think chemistry is a real phenomenon? And do you think it can build, after two years? I have such a great time with him and he treats me with the upmost respect, so if I felt more on that level this situation would be ideal.
Also, do you think it is better to go on a break from him to sort out my head (yet risk losing him) or move there and try to see if we can develop certain elements (my only concern with that being that if we are still having fun together a few months down the road but I am still unsure about marrying him... what will I do)?
Thank you for your advice!
