Hi! So i've been using this site alot for the last year.. And this will be my first post!
Please excuse my grammar as english is my second language.

Littlebit background info: Been dating this girl for 4 months, she is a tall blonde (HB9!)
She has bipolar disorder, but there havent been any problems around that as she is taking her meds.
It's a LDR (2,5-3 hours drive) and it have been working out very well for us. Her mother and my mother are best friends, so we have known each other for some time. And i've always been her childhood crush.

In my other relationships ive been more of the beta type of guy.
So I have been trying my best to be an alpha in this relationship, and it worked out pretty good.. until last weekend when i visited her.

When we were about to go to bed she kept texting one of her girlfriends, who had trouble with some guy she was dating. I was tired and wanted to get some good sleep before i left in the morning. After some texting back and forth her phones start ringing, she said it was her girlfriend and she had to take it. She answers the phone and i hear a masculin voice in the other end. I confronted her after she hanged up the call, and i overreacted. Her getting a call from a guy wouldnt bother me that much, as she as alot of guy friends. But i got mad because i tought she was lying to me. It did turn out to be her girlfriend that called, so i apologized and said that i overreacted.

I didnt text her the day after i got home, and i got a text from her why i havent texted her.
I replied that i had worked with my exams, so i've been busy. Which was true.
There has been some texting back and forth but she is delaying her texts much more than usual and sometimes she doesnt even reply back. So i decided to not contact her for a while.

I had planned to take her with me on a vacation, so i contacted her yesterday to say that i couldnt go because its right after school ends and alot of my friends are gonne be back in town.
She got kinda mad and we havent talked since. (she liked my pic on instragram yesterday tho )
The plan now was to go no contact for 3-7 days

Am i doing the right thing here? I really really like this girl, and i would be depressed if this doesnt work out for us :S
