I don't know how I get myself into these things

I'm a person that suffers from depression but is lucky enough to only suffer the intense effects when there's a problem in my life. I'll go years with no real problems, but now I've got a real problem. I really screwed up. I made a huge mistake. I let me guard down and let myself into a situation that I wasn't prepared for. I trusted someone that took advantage of me and made ME hurt the person I care about most. Okay, I'll stop tip-toeing around what happened. Last spring my boss kept inviting me to parties at his house. He invited me every single weekend and I had an excuse every single weekend. I'm a student working my way through college so homework usually provided me with more than enough excuses. See I had heard stories about some of these parties. They tended to get a little wild by the end of the night. They started with kids running around and ended with people naked in his pool. He would actually tell me, his secretary, about this. But eventually I started to feel like I should attend one out of respect (and he was starting to make me feel guilty). I thought it would be good for my career with the company. He told me about one party that all of his family was going to at. His parents, his sisters, some other people from the company, and lots of kids. So, I decided to attend with my boyfriend, stay for 2 hours and leave. Well, when we got there my boss was belligerently drunk. He kept making comments about my skirt. Right there I should have left. But I'm a very passive person. I hate confrontation. I'm a very 'run with the pack' kind of person. It's not something I'm proud of. I get a lot of social anxiety. Well, because of my social anxiety and because I was so uncomfortable I started drinking. A little too much. I got drunk. It was about 8 o'clock when I got up to go to the restroom. My boyfriend said he saw my boss jump up a few seconds after I went inside and follow me in but he didn't think anything about it. When I came out of the bathroom and walked through the kitchen (stumbled more like). He pushed me into a corner and kissed me. I pushed him away and reached for the door to go back outside. I was too drunk to deal with that situation. All I could think about at that moment was my boyfriend. All I wanted to do was get out of there. I immediately walked straight up to my boyfriend and told him what happened. I didn't want to be anything but honest with him. I honestly don't remember his reaction. The next thing I know my boss is standing behind me with his hands on my breasts. My boyfriend pulled me to the car and we left. My boss is an unimaginable jerk. But the horrible thing is that I still work for him! It's been almost a year and I can't find another job. Especially one that will allow me to take time off to go to class. Every time I see him I want to punch him. I'm so angry and I have no place or nothing to do with my anger. I just keep eating it and it's eating me up inside. I come home crying all the time because after an entire day of putting on a brave face, I break down on the car ride home. But my boyfriend says we can't afford for me to quit. Even for me to get a job that pays less. I'm scared that he thinks that I was in some way asking for it. Or he's subconciously punishing me by not letting me quit. A few months ago I told my mom about what happened and she said she'd help out financially if I quit too. I'm just so unhappy and mentally exhauted.
