<human>: Background Knowledge:

I've been dating my SO for two years. Our first year was spent long distance, and it was probably the worst year of my life. While the beginning of our relationship was amazing (still that honeymoon phase), once I came back to my home state for winter break, spent months with him having an amazing time, and then left for school again, I became really depressed. He hardly talked to me, and when he did it was to tell me he couldn't trust me or I was a liar. He pretty much tore me down limb from limb. I felt like I was walking on eggshells in the relationship- if I told him I was hanging out with friends, he'd stop talking to me for a week. If I told him I was going to the gym, he'd wouldn't Skype me that night. Etc. (I should note that he has some mental conditions-- anxiety, depression, bipolar disorder, and schizophrenia, which all make him paranoid)

When I came back to my home state for summer break I decided to stay and go to college here. I was so depressed, and my family helped me through the process so much. I stayed with my bf and things got so much better. I feel like we grew together through the summer and the next year. He no longer had problems with me doing my own thing. I helped him take his medications and we spent lots of time together. We grew a lot more comfortable in the relationship and trusted each other a whole lot more.

The thing is, I really want to study abroad this next semester. It would be for three months in London. But if my bf starts acting like he did when we were first dating, I honestly don't think I would make it. I love him, and don't want to break up. In an ideal world I would go abroad and have an amazing time while knowing my boyfriend would trust me and be there when I get back.

He'd never go abroad with me because he's working and in school, so that's not an option. But I desperately want to travel. I don't know what I should do. Expect the worse? Not even travel? Tell him to fuck off and chase my dreams?

Can you condense the text into a few key points?
<bot>: My boyfriend and I have done long distance before and it sucked. Now thinking of studying abroad for 3 months, but not sure what's going to happen.
