If you want my piece of advice, I think your main problem is that you're in a new city being lonely and sad.
That's why you put so much meaning in #1:s texts etc.
So I would advice you to focus on yourself, to keep busy, start new hobbies, get to know the new city and have fun. Don't put so much pressure on your relationships, let them develop in their own time.
If you are happy and comfortable in your own skin, your relationships will thrive too.
I'm currently struggling with same kind of issues, so I've started a regular meditation routine. Even that kind of little effort helps!
