As has been said, just be careful that you or she are not holding in your emotions out of fear of upsetting the other. Arguments are healthy for a relationship. Get things out when they happen instead of getting barraged with stuff you did 3 months ago.
Sounds like that's not the problem though, so congrats.
But, you're also missing out on makeup sex. And no, if you haven't had it yet, don't bother saying the sex you have now is already great. Once you have makeup sex, you'll find ways to piss her off just so you can HAVE makeup sex.
