So the story is really complicated but I don't know how to move on with my life after it.
To summarize, I got married 4.5 years ago and we moved here together. From the beginning he constantly threatened me with divorce which took its toll on my mood (I tried commiting suicide a few months after moving here). I never wanted to cheat but in addition to threats of divorce, he always called me oversexual and suggested I see a doctor (I wanted sex once a day... not unusual for a guy). Despite all of this I worked hard at a job I hated to support the both of us (he wouldn't work, he was a full time student and could have worked to help me, but he didn't want to do anything not related to his field of study).
Anyway, fast forward we got our green cards (from my work that I only stayed at for him). A few months later he started dating (we were trying an open relationship but dating was not supposed to be allowed). He also lost "part" of his virginity to the guy he was dating and who is now his current boyfriend. He went back home to visit for the summer and asked me for a divorce 7000 miles away. We agreed to try and work through it, but meanwhile he was having sex with lots of different guys and he got back here only to mislead me and get me to still pay for his expenses despite being in love with someone else. He claimed "I can't decide about our relationship if I don't have food" so of course I bought him food...
I'm bipolar and I have tried years and years of medications with no luck. Earlier this year I started smoking meth which I know is not good for you. I minimize the risks as much as possible of course and I can hold my own in an argument about whether it's actually as bad as the media portrays (for example, I know hypertension can cause LVH which is a serious risk factor for things like sudden cardiac death, not to mention aortic dissection and congestive heart failure... I want to be a vet lol).
So here's the thing, smoking meth helps prevent my suicidal thoughts, but I do want to give it up and start focusing on my future. I need help though. Logically I don't want to be married to him, he's a terrible person (you can't say deep down he's a good person, I left out something very big because it's too painful for now, but I can share if it helps you help me :-( ).
How can I move on from what he did? I just can't seem to do it. Logic is failing me which really sucks. What has cheered me up lately is accepting the fact that I think I'm done with relationships. I've had it, and I don't want it. You can say I'm jaded, I'm just in shock, or I'll change my mind one day, but it's the only thing that helps me when I'm feeling down. Recognizing that that part of my life is over. I do have a long road ahead of me, vet school (hopefully) but first I have to work about 2 years to save up for it. But despite a great plan, I can't get over it. It doesn't help that he's not cooperating at all with the divorce (which I now want of course). So now I'm filling out the papers and paying for my own divorce... that's really some twisted stuff right there. See? He's not a good person.
Please help because the suicidal thoughts are stronger than ever. I tried going to a psychiatrist to get on meds again and he said he wouldn't prescribe me anything for at least a few weeks.... I've been on at least 10 bipolar meds and he's making me wait with vivid suicidal thoughts... first, do no harm?
Can anyone help me please?
