@sw26,
You're definitely on different paths. His is - I have a girl but I won't let her see my pals. Yours is, you want to be in all aspects of his life.
Recognize that people are going to have separate groups of friends and there is nothing wrong with that. What is an issue is if you are
never brought along. If you are kept totally separate, then you gotta wonder, is there a reason for that? But if you aren't brought along to every single event, I'd say, that's fine (and take advantage of that time, and see your friends or grab some me-time).
As for him not wanting to be in touch every day, and not confessing love, there are folks like that. Not wanting to be in touch every day can be a sign of a flagging commitment, particularly as you aren't dealing with distance. Even with a difficult work schedule, he should be able to tap out a quick text -
thinking of you, want to go to the movies on Friday, I can't go out this weekend as I promised my mother I'd help her clean out her garage, whatever.
The lack of a confession of love can be troubling, but people do come to it at different times. You have been together for nearly a year and a half. I'd like to think he knows it by now. But for some people, it can feel cheapened if they say it too much, or they don't say it in the context of marriage or at least a ring. Frankly, I'd be beginning to wonder about that myself. You've been together for a significant period of time by any measurement. Where is this going?
That conversation, about where things are going - BTW - for shaky relationships, it is often the final nail in the coffin. But at least you'd know, and you'd be free to pursue others. Want to have that conversation? Then do so, the next time you are alone together. But don't be surprised if it doesn't turn out the way you want it to.
