For the past year I've been having a crush on a friend of mines online. We've never met but just know what we both look like through our Facebook pictures and a few times that we've webcam. I like him but lately I feel upset at everything he does. Honestly I don't think I trust him even though I want too. I don't understand why? Whenever other women flirt with him online or he mentions other girls to me I just get extremely upset. I even have problems with overthinking things and assuming too much. It makes me a very upset and stressed out person these days. How can I control all these emotions? I feel like it's slowly ruining me and making me become a very unhappy person. And also my friend gets upset too when I act this way, he tells me I don't trust him enough. He also told me that we can't be more than friends until we meet and see if we're compatible or not. Hearing all that makes me even more upset. So yes I have a terrible emotional problem. How would you guys go about fixing it?
