We actually live pretty close together, but since she gets home around 10:30 and I'm up at 5:30, but that said, even some nights I do want to see her for a bit and she usually isn't up for it, there is really limited time during the week we could see each other, sometimes I struggle just to stay awake to talk to her when she gets home.
Yes, the puppy is definitely an affection drain, she smartly acknowledged it a few weeks after she bought it that she knew it was time consuming, and told me not to worry or be jealous, that for now that will be her priority and I have to accept it as a package deal. I know she does try to make time for me on the weekends, but her attention is almost always divided between me and puppy. I can't hate the dog, its nice, but I can resent the timing on her decision to buy it. But I know it is still a puppy, keeps her up most nights, and takes up a lot of time.
We're both mid 20s, I'm 26 and she is 24. We are both looking for long-term, but right now we're in different places I think.
That said, a week or so ago she sent me a long text message saying how sorry she is that she is being the way she is, and that she will come around and make all my effort worth it if I just be patient. That was probably the most positive message I've gotten from her in a while.
edit: we already met the families, last weekend we did Easter dinner at her family's place, then the next night at mine.
