I'm not so good with subtlety, but I would suggest try something like not calling them.
If they haven't called you in a week, they are not as interested in you as you would like them to be.
You could then call them and ask why they didn't call, and whether they are interested in you.
As I said I'm not one for subtlety, so it may even be best to skip all the game playing and just ask them outright; "are you interested in me, do you want to hang out, or am I misreading the signals you are sending?"
No need to mention why you feel confused, but just seek clarification.
All you can do is be honest, communicate to the best of your ability; which may mean texting, emailing, or messaging if you have difficulty with verbal communication - I know I often do - so at least you can make sure your message is clear.
If it's all guess work, subtle cues, and hard to understand, it may mean they're not as interested in you as you are in them, especially if you raise your concerns with them and nothing changes.
I can't give you all the answers, but I can tell you that I am married have been for 6 years, and my marriage works because I constantly communicate with my wife, phoning, emailing and texting her every day, often even an hour after she has left home, or an hour before she leaves work.
The only way to maintain good relationships is with communication, and if there is no communication there is no relationship.
