I'm lost on what to do...

Even with the use of condoms, birth control, and being told due to slight scarring, I ended up pregnant. 13 weeks. The father was my best friend who I live with. He told me that we were together and that he would help me through it all. He ended up confessing to seeing girls while off to training for his deployment. He keeps backing out of everything that would come to help with the baby. He went and raised my rent leaving me with no money. I'm scared I'm in this alone and I have no idea where to go get help financially until I'm back on my feet. I'm horrible at researching and can't seem to find the right things. Does anyone have any advice that could help me?
