I hate to say it, but you've got to consider over the life of the relationship how needs are being met and where compromises are being made. You can't compromise all the time. Also, after the honeymoon period (which I assume you're over), a relationship has got to be a source of security and comfort without extra effort from one person beyond which they are willing to give for the rest of their life.

It seems like you're really trying, and that it is your dissatisfaction that's really present, and not so much his. Seems very hard problem. It's possible he has a crush on Morgan, which would make him temporarily less interested in you, but I don't know enough.
