<human>: This happened a couple hours ago.
My girlfriend of almost 2 years broke up with me. She isn't very specific about the details, but she said "i should watch who I talk to and what i say about her" and that she was done with me. Me thinking I can't really think of anyone I hold close enough that I would talk to about let's call her Jessica. 
I'll start off by saying we have a kid on the way and that scares me even more because now I might have to fight for my child. 

There has been points in our relationship where Jessica has caused a fight or I may have myself and I say stuff that I don't mean but never directly too her, but always to people I trust. She won't even explain to me who said what or even what was said. So i cannot begin to solve this problem with her, and the fact that she trusts them over anything I would say to her really grinds my gears because about 6 months in our relationship she left me for a month and started dating one guy and then had sex with another and i took her back no questions asked and still had full trust in her and would let her explain herself before i ever accused her of something. Our relationship seemed like a lot of me doing the work and this is any easy way out for her. 
It's going to be a long and messy road ahead.

Can you summarize the given text in a few sentences?
<bot>: Girlfriend is pregnant, she left me because something I said out of frustration to someone i trust and wouldn't even confront me about it.
