This goes against everything you think will work. But tell me, the things you want to do, did they ever work in the past in other relationships?
Fyre, you can call her. I wouldn't, but you can. Eventually you'll figure out that the contact you really want, she isn't going to provide. You want the type of contact that is comforting from her, but what you are more than likely going to get is contact that is going to end up hurting you.
So let's say you do call her. What are you going to say?
"Hey. I miss you." BAD
"Hey, just thinking of you, hoping your having a good day." BAD
"Hi, I love you." WORSE
Any of those emotionally laced statements will generate silence, and then your going to get upset and wonder what is wrong with her...from there...it goes downhill. Do you like arguments? Do you want to feel worse than you do right now?
It is not childish. It may very well be the most miserable time of your life. Lets hope it is, lets hope nothing worse happens to you or yours.
So you are very new to this.
What are you going to do today for yourself? What have you not done for yourself in a very long time? What can occupy your mind? Go do it. In fact go do something that you would never see yourself doing, Rock Wall Climbing, Pottery class, Art Class, join a Museum. Something new that will require you thinking outside your safe box zone.
